Dear Readers The year of hopes has come. 2020 has already become a matter of past and our scientists have found a solution for the pandemic that is the invention of the vaccine. These things have proved that humanity is not going to vanish by mere conspiracies of a nation. We are overcoming the pandemic and it is clear that humanity has won this war against COVID-19. The things were not well enough last year for the economy but the construction and developments of Metro and Rail's networks achieved have been very excellent even during the pandemic. The things are improving for the economy but the Metro and Rail Sector is already achieving new heights. The Water Metro in Kerala is also a very new thing for the nation.

COVER STORY
REVOLUTIONIZING
Transport Through Maglev
The technology which we are featuring this time as our Cover Story is non-other than the Maglev Train which is also known as magnetic levitation train. It is a floating vehicle which is used as a mode of land transportation. The technology is supported either by electromagnetic attraction or repulsion. The magnetic field created by the electromagnetic waves helps the technology to carry on with its work with an amazing speed. The concept of Maglev was formulated during the early 1900s by American professor and inventor Robert Goddard and Frenchborn American engineer Emile Bachelet. The commercial use of the technology started in the year 1984 and since then, many networks and operators are working for the development of extensive networks proposed for the future for different countries especially the Asian ones. Maglevs incorporate a basic fact about magnetic forces—like magnetic poles repel each other, and opposite magnetic poles attract each other—to lift, propel, and guide a vehicle over a track. It is a basic science which is used in an advanced mode through the concept of electromagnetic waves. Maglev propulsion and levitation generally involves the use of superconducting materials, electromagnets, diamagnets, and rare-earth magnets as of now. Electromagnetic suspension known as EMS in short form uses the attractive force between magnets present on the train’s sides and the underside and on the guideway to levitate the train. A variation on EMS, called Transrapid, employs an electromagnet to lift the train off the guideway. The attraction from magnets presents on the underside of the vehicle that wraps around the iron rails of the

guideway keep the train about 1.3 cm above the guideway as per the studies conducted on the technology. These magnetic fields interact with simple metallic loops set into the concrete walls of the Maglev guideway. The loops are made of conductive materials, like aluminium, and when a magnetic field moves past, it creates an electric current that generates another magnetic field. Electrodynamic suspension (EDS) systems are similar to EMS in several respects, but the magnets are used to repel the train from the guideway rather than attract them. These magnets are supercooled and superconducting and have the ability to conduct electricity for a short time after power has been cut. Unlike EMS, the charge of the magnetized coils of the guideway in EDS systems repels the charge of magnets on the undercarriage of the train so that it levitates higher (typically in the range of 1–10 cm) above the guideway. EDS trains are slow to lift off, so they have wheels that must be deployed below approximately 100 km per hour. However, these trains are not considered as much popular in comparison with the other ones. "Three types of loops are set into the guideway at specific intervals to do three important tasks: one creates a field that makes the train hover about 5 inches above the guideway; a second keeps the train stable horizontally. Both loops use magnetic repulsion to keep the train car in the optimal spot; the further it gets from the centre of the guideway or the closer to the bottom, the more

magnetic resistance pushes it back on track", according to an expert. The third set of loops is a propulsion system run by alternating current power. Here, both magnetic attraction and repulsion are used to move the train car along the guideway. Imagine the box with four magnets -- one on each corner. The front corners have magnets with north poles facing out, and the back corners have magnets with south poles outward. Electrifying the propulsion loops generates magnetic fields that both pull the train forward from the front and push it forward from behind. "This floating magnet design creates a smooth trip. Even though the train can travel up to 375 miles per hour, a rider experiences less turbulence than on traditional steel wheel trains because the only source of friction is air", he adds.
Maglev generally eliminates a key source of friction although they must still overcome air resistance. There is no friction related to rolling stock and tracks and finally, this lack of friction means that they can reach higher speeds than conventional trains. At present maglev technology has produced trains that can travel more than 500 km per hour. This speed is twice as fast as a conventional passenger train. Because of air resistance, the maglevs are only slightly more energy-efficient than conventional trains.
Benefits And Costs Maglevs have several other advantages compared with conventional trains. They are less expensive to operate and maintain because the absence of rolling friction means that parts do not wear out quickly. This means that fewer materials are consumed by the train’s operation because parts do not constantly have to be replaced. The design of the maglev cars and railway makes derailment highly unlikely, and maglev coaches can be built wider than conventional Rail or Metro Coaches which further offers more options for using the interior space and making them more comfortable to ride in. Maglevs produce little to no air pollution during operation as no fuel is being burned, and the absence of
friction makes the trains very quiet. The maglev systems can operate on higher ascending grades than traditional Rail tracks. It also reduces the need to excavate tunnels or level the landscape to accommodate the tracks compared to traditional Rail or Metro networks. The greatest obstacle to the development of maglev systems is that they require entirely new infrastructure that cannot be integrated with existing rail tracks and that would also compete with existing highways, rail tracks, and air routes.

COVER STORY
Besides the costs of construction, one factor to be considered in developing maglev rail systems is that they require the use of rareearth elements (scandium, yttrium, and 15 lanthanides), which may be quite expensive to recover and refine. Magnets made from rare-earth elements, however, produce a stronger magnetic field than ferrite (iron compounds) or alnico (alloys of iron, aluminium, nickel, cobalt, and copper) magnets to lift and guide the train cars over a guideway. Several train systems using maglev have been developed over the years, with most operating over relatively short distances. Between 1984 and 1995 the first commercial maglev system was developed in Great Britain as a shuttle between the Birmingham airport and a nearby rail station, some 600 metres away. Germany constructed a maglev in Berlin (the M-Bahn) that began operation in 1991 to overcome a gap in the city’s public transportation system caused by the Berlin Wall; however, the MBahn was dismantled in 1992, shortly after the wall was dismantled. Six commercial maglev systems are currently in operation around the world. One is located in Japan, two in South Korea, and three in China. The Korean Rotem Maglev runs in the city of Taejeŏn between the Taejeŏn Expo Park and the National Science Museum, a distance of 1 km. The Inch’ŏn Airport Maglev has six stations and runs from Inch’ŏn International Airport to the Yongyu station, 6.1 km away. The longest commercial maglev system is in Shanghai; it covers about 30 km and runs from downtown Shanghai to Pudong International Airport. The line is the first high-speed commercial maglev, operating at a maximum speed of 430 km per hour. China also has two low-speed maglev system operating at speeds of 100 km per hour. The Changsha Maglev connects that city’s airport to a station 18.5 km away and the S1 line of the Beijing subway system has seven stops over a distance of 9 km. Japan has plans to create a long-distance high-speed maglev system, the Chuo Shinkansen, by 2027 that connects Nagoya to Tokyo, a distance of 286 km. It is indeed a very ambitious project of Japan. With an extension to Osaka which is 514 km away from Tokyo) planned for 2037. The Chuo Shinkansen is planned to travel at 500 km per hour and make the Tokyo-Osaka trip a 67 minutes journey. In the system of magnetic repulsion and attraction, once levitated, however, the train is moved forward by propulsion provided by the guideway coils, which are constantly changing polarity owing to alternating electrical current that powers the system. "With no wheels and only one track, Maglev trains would poohpooh bad weather, the wrong type of leaves on the line, or a points failure at Cricklewood. Because of the way maglev (in various ways) repels the train above its track, derailments are unlikely: the further the vehicle gets from its track, the stronger the magnetic force pushing it back. No signalling or moving parts to go wrong, with all the trains travelling at the same rate. Imagine the effect on commuting and by extension the economy – the Midlands would be half an hour from London", a researcher says. Magnetic levitation (maglev) was, according to 1980s science shows such as Tomorrow’s World, going to make domestic air travel defunct, humming from city to city at 500mph with negligible effects on the environment.

Japan has plans to create a long-distance high-speed maglev system, the Chuo Shinkansen, by 2027 that connects Nagoya to Tokyo, a distance of 286 km (178 miles), with an extension to Osaka (514 km [319 miles] from Tokyo) planned for 2037. The Chuo Shinkansen is planned to travel at 500 km (310 miles) per hour and make the Tokyo-Osaka trip in 67 minutes. There are now several other maglev projects in progress in Asia; the best known perhaps being the unmanned EcoBee shuttle that travels to and from South Korea’s Incheon airport. This shortish line linking seven stations along which the shuttle travels at the comparatively sedate at a very High Speed. In Maglev, superconducting magnets suspend a train car above a U-shaped concrete guideway. Like ordinary magnets, these magnets repel one another when matching poles face each other.
The Japanese Story In 2009, the Maglev system was approved and entered commercial construction. The Linear Chuo Shinkansen line is planned to link Tokyo and Nagoya by the year 2027. The trip is expected to take only forty minutes – faster than either flying between the two cities or taking the one and a half hour trip on the current Tokaido Line, available with the Japan Rail Pass. The proposed route will include stops at stations in Shinagawa, Sagamihara, Kofu, Iida, and Nakatsugawa. Ever since it was launched in time for the 1964 Olympic Games in Tokyo, the Shinkansen has remained a source of national pride in Japan. The story of the bullet train is also one of progress. When it first linked Tokyo to Osaka over half a century ago, it was at a speed of 210km/h; today, trains hurtle along at a clip of up to 320km/h, transporting over a million passengers a day. But as the Shinkansen has developed into something of an institution – and emblem of the country’s technological spirit – the next chapter of high-speed train travel in Japan has proven much harder to write. The original goal of the Maglev project was to produce a train that could cover the route from Tokyo to Osaka in less than one hour. This will be achieved when the Maglev line is extended from Nagoya to Osaka, expected to be in operation by 2045.
COVER STORY
Eighty per cent of the 286 kilometres Maglev bullet train track will be located underground, passing under urban sprawl and mountainous terrain. The project is expected to cost the equivalent of 55 billion dollars. When completed, the train will include sixteen carriages capable of holding one thousand passengers. At present, the public has been invited to take part in Maglev test rides. Tourists can visit the SC Maglev Parkway in Nagoya or the Yamanashi Prefectural Maglev Exhibition Center near the town of Otsuki to learn more and view Maglev test runs. The Chuo Shinkansen The Chuo Shinkansen (or the Tokaido Shinkansen Bypass) is a new rail line which will connect Tokyo and Nagoya. It is being constructed in phases and will use cutting-edge Maglev (Magnetic Levitation) technology. Once completed, the line will provide a more direct line between the two cities and will reduce travel time by around 50% (down to 40 minutes) in comparison to the current Tokaido Shinkansen line. The route will be extended to Osaka once the project progresses – the whole journey will take just 67 minutes. Passengers will be able to get tickets for the new line in 2027. The trains will travel at a maximum speed of 505 km/h (the world record is 603 km/h). The route map will initially include 6 stations: the Shinagawa Station, the Nagoya Station, and the prefectures of Kanagawa, Yamanashi, Nagano, and Gifo. It will include 256.6 km of tunnels, 11.3 km of bridges, and 4.1 km of rail beds. The Central Japan Railway Company (JR Central) is overseeing the project which will cost an estimated 5.52tn yen ($52b). They have ordered 14 new Series L0 (L zero) Maglev trains which are currently conducting long-distance trials on the Yamanashi Maglev test line.
Other Aspects The Maglev may hold the current world records, but it will have its competitors. Japanese prime minister Shinzo Abe has proposed selling the technology to the United States to build a Maglev line between New York and Washington. At the same time, plans are underway for the Hyperloop train line from Los Angeles to San Francisco, California, USA, that may reach speeds in excess of 700 miles per hour. In the meantime, the highspeed hopes of Japanese citizens and tourists alike rest squarely on the Chuo Shinkansen Maglev line. The European Scene The first commercial maglev rail line operated from Birmingham airport for about 11 years before high maintenance costs saw it shut down. Other countries experimented with the technology, but activity ground to a halt after 23 people lost their lives in a 2006 crash between a maglev train and a maintenance vehicle in Germany. The European nations are very far behind in adopting the technology as compared to the Asian nations. However, the experts suggest that despite this, there is still some way to go. The European nations may try to adopt to the technology in a very new and peculiar way in the very near future.
The Indian Perspective The government-run engineering firm of India, BHEL in September 2020 announced its tie-up with SwissRapide AG to bring Maglev trains (magnetic levitation) to India. Aimed at expanding its footprint in the urban transportation sector as part of its diversification initiatives, BHEL has entered into a Memorandum of Understanding (MoU) with SwissRapide AG for Maglev Train projects in India, a company statement said.
COVER STORY
The Maglev Rail system hovers in the air instead of rolling, due to magnetic levitation, thus the vehicles have no physical contact with the guideway. This enables the system to be highly energyefficient, allows operating speeds of easily up to 500 km/h and significantly reduces the total cost of system ownership. The MoU was signed by S V Srinivasan, GM & Head (Transportation Business Group), BHEL and Niklaus H Koenig, President and CEO, SwissRapide AG. The agreement has been signed in the backdrop of the Prime Minister's 'Make in India' and 'Aatmanirbhar Bharat' initiatives and will enable BHEL to bring the latest, world-class technology to India and manufacture state-of-the-art Maglev trains indigenously. According to officials related to the Development, Mumbai may well become the first testing ground for this new transportation technology in the country which will further transform the way of public transport especially the High-Speed transport system of the country. "The Mumbai Rail Vikas Corporation (MRVC) is proposing to introduce the technology on the Chhatrapati Shivaji Maharaj Terminus (CSMT)-Panvel elevated fast corridor on a public-private partnership (PPP) model", according to recent development.

SwissRapide AG has proposed for executing the project at a cost of nearly â‚š13,347 crore. This clearly shows that India is progressing very fast in every field and it aspires to become a NextGen leader in the middle of this century.
EXCLUSIVE INTERVIEW
Our Founder and Managing Editor Mr Narendra Shah had a brief conversation with Mr Rakesh Gaur, President of Railway Division at Kalpataru Power Transmission Limited.
Here are some excerpts from the conversation:Narendra Shah - How do you take your association with the firm? What are your responsibilities here in your company? Please also tell something about your works? Rakesh Gaur - I am the President for Kalpataru's Railway Division and I am accountable for Group Railway Business globally. My association with the firm is 2 year old and I am with the industry for more than 30 years. We execute all kinds of Railway projects and we operate with Indian Railways especially in the domain of Electrification, Signaling and Telecommunication, Traction Sub Stations and Composite Track jobs, track modifications, gauge conversion, major and minor bridges, Station building and associated works like Platform etc. Narendra Shah -What do you think about the condition of the power sector in India when it comes to Railways and Metros? What are the future perspectives ahead in this business?
Rakesh Gaur President of Railway Division at Kalpataru Power Transmission Limited.
Rakesh Gaur - The power sector in India is in a very good shape in terms of stability and capability. We have a very stable Grid. But, if we see it in context of Indian Railways, we are going to electrify approximately 68,000 Route KM (RKM. If we electrify the complete 68,000 RKMs we will have approximately 1000 Traction substations, 4000 switching posts and around 2000 feeders will come in for Railway connectivity and it will require connectivity at various grid levels of different electricity boards. In terms of power consumption, 2% of Country’s total power generation is generally consumed by Indian Railways. They are the largest consumer of power and consume 85% for traction works, and 15% for amenities, station works and other non-traction works. At present, since the complete network is not electrified and the electrification is done for only 42000 RKM, diesel is also being consumed on un-electrified routes METRO RAIL NEWS | January 2020 | WWW.METRORAILNEWS.IN

EXCLUSIVE INTERVIEW and approximately 3.2% of total diesel consumption of India is being consumedbyIndian Railways. With High Speed Rail Corridors, DFCCs and other projects which will come into operation, the power quality will also become an issue and Indian Railways is upgrading the network to meet this requirement. In the Railway plan, they have already forecasted setting up 1000 MW of Solar Power and 150 MW of wind power and they are also working on the quality of power utilizing the dynamic filters to reduce the harmonics level at Traction Sub Stations.
Narendra Shah - Kalpataru Power is already one of the leading players in this sector? How do you take it, and what are the challenges ahead? Rakesh Gaur - KPTL is one of the leading players in this sector and we feel really proud that within a short span of time we are contributing significantly in the field of Railway Electrification which is a dream for Hon’ble Prime Minister and the Minister of Railways and approximately 20 to 25% contribution in this field is coming from KPTL on yearly basis now. The major challenge that the industry is facing post lockdown or you can say during COVID-19 is Cash Flow. Productivity levels are low. The availability of cash is limited, Capex orientation is getting changed and pace of execution is also becoming a major challenge because we have to meet the targets but there is a shortage of manpower. This is a logistically challenging situation for the movement of manpower and has a cascading effect on the pace of execution, however we are sharply focused on addressing this matter. The other concern is that of Commodity prices.

METRO RAIL NEWS | January 2020 | WWW.METRORAILNEWS.IN
We are witnessing a sharp uptick in input cost and they are rising in a very unpredictable manner because of the larger Geo-Political issues. For Railway Electrification sector, the rising prices of Steel and Copper are also posing a major challenge. Narendra Shah - What are the different Metro and Rail organizations you are working with today? How are you connected with the Metro Corporations? Rakesh Gaur - We are associated with most of the Zonal Railways. With RVNL, a major PSU, we are executing the composite as well as electrification projects. Our other prestigious projects are with CORE and PGCIL, Gujarat Railway Industrial Development
Corporation, Konkan Railways as well as RITES. We are participating in tenders and remain hopeful of a business breakthrough with DMRC and other Metros for execution of Electrification works. Narendra Shah - Which segment of the business, you are going to focus in the near future ? Is there any plan lying with you to bring new innovations in the business? Please share your views. Rakesh Gaur - As a group our focus is always on diversification to facilitate growth but that growth should be a profitable one. We are first building up on our capacities in our core areas i.e. we are doing Composite, Signaling as well as Railway Electrification projects. So these are our focus areas and we will continue to focus on these areas. However, we also want to see how our resources can be optimized by diversifying our portfolio, we are going for ballast less tracks as well as for international opportunities. We are mapping the other spectrum of the Railway business like RRTS or further corridors of DFCC etc.
EXCLUSIVE INTERVIEW In terms of Mechanization or Digitization, our efforts are for the overall optimization with the available resources. We have gone for wiring train as well as for Flash butt Welding machines of our own. We have gone for RRV and other such equipment which will give us an edge to improve the productivity for track works. Narendra Shah - How has your company performed in the last quarter? Is there any major impact of the pandemic over your business? Rakesh Gaur - As you know after March’20, every company had a setback in the first quarter because of uncertainty and anxiety over labor movement and complete lockdown of the system. But, from June onwards, we have recovered well and our last quarter was on target w.r.t projections and we are meeting all the targets which have been set and agreed by us with Ministry of Railways. We are continuously doing the CRS and even today a CRS is going on a critical section. We are meeting all the projections and targets. The initial setback is behind us and now we have fully recovered from that. Narendra Shah - How has the ongoing Coronavirus Pandemic changed the way of Railway business? Is there any major change being observed in this sector? Kindly express your opinion. Rakesh Gaur - The disruption due to COVID-19 has really changed the way of thinking and ways of doing business. For construction activities people have to be at site and we are now trying to see how to optimize the output of our labor. Similarly, initially the speed of execution was a bit slow because of
the labor movement restrictions and there was a lot of anxiety among people. Now the anxiety levels have settled down, migration and reverse migration is taking place. However, since the trains are not running to full capacity, the labor movement is restricted and we have to bring the manpower through luxury buses. The safety and hygiene protocols as well as camping arrangements have changed drastically at the sites. Due to restrictions of train movement , the availability of the blocks for working on the nearby tracks is slightly better. Industry is seriously thinking of more mechanization, more digitization and reworking the earlier practice of gathering of labor in any particular area to ensure social distancing. Narendra Shah - In which of the foreign countries, you are currently working with? Kindly Share the details. Rakesh Gaur - KPTL started their operations as a power transmission and distribution company and that is our core strength. We operate in around 50 countries at present covering all the continents and we have significant presence in Central Asia, Africa, SAARC countries etc. In the Railways business, we have started working in Bangladesh. We are executing a Joint Venture project in a very congested area of Dhaka and the project is moving well inspite of initial setback due to COVID-19. The project progress has now come to the normal expected levels. Narendra Shah - Please share a message for our readers. Rakesh Gaur - My congratulations to you as well as to the readers as we are getting a platform where we can interact, share our experiences and get updated on the developments across the industry. Friends, there cannot be a better time than now to start using local components and becoming more “Vocal for Local” and it is our esponsibility to ensure that our quality is top notch and better than Global standards. I remain hopeful that 2021 will be better and erase the pain we had to endure last year. I wish all of you good health, prosperity and happiness. My Best Wishes to you all. Narendra Shah - Thank You
FEATURED STORY
The Story of Driverless Trains
Authored By..
Narendra Shah Managing Editor METRO RAIL NEWS
After a long wait since 2017, the Delhi Metro Rail Corporation (DMRC) entered the elite league of 7 per cent of the world’s metro networks that can operate without drivers in December 2020. The DMRC has got the credit of being the only Metro Corporation in the country to have the technology with the launch of the country’s first ‘driverless’ train on its Magenta Line which runs in the national capita connecting Delhi and parts of Noida. Prime Minister Narendra Modi flagged off India’s first driverless metro via video-conferencing. Delhi Chief Minister Arvind Kejriwal and DMRC Managing Director Mangu Singh were among other senior officials who attended the event. The train will be fully automated, eliminating the possibility of human error, according to DMRC officials. The service will be available on Delhi Metro’s 38-km long Magenta Line which connects Janakpuri West in West Delhi to Botanical Garden in Noida in the initial months and then after it will be extended to the pink line of the DMRC network. "DMRC has had driverless technology since 2017, but the agency had been conducting rigorous trials before launch. The initial launch was set for May 2020 but it had to be postponed due to the Covid-19 lockdown", says an official.

The automated train systems use the Grade of Automation classifications specified by the standard IEC 62290‐ 1. Technology needs an enhanced signalling system. The history of Metro automation is not very new to the world. Indeed, it has been a long period. The first line of its kind to be operated with Automatic Train Operation (ATO) was London Underground's Victoria line, which opened in 1967, although a driver was present in the cabin. However, as if now, many lines now operate using an ATO system, with the aim of improving the frequency of service. Since then, ATO technology has been developed to enable trains to operate even without a driver in a cab: either with an attendant roaming within the train or with no staff on board. With these developments, Port Island Line in Kobe, Japan became the first of its kind to have in the year 1981. It was the first fully automated driverless mass-transit rail network. The second in the world is the Lille Metro in northern France which became the first driverless network of Europe. Autonomous driving seems like new technology, but its history is surprisingly long. The world’s first automated unmanned railway was Kobe New Transit’s Port Liner which commenced operations in 1981. Although nearly 30 years have passed since then, automatic railways are not spreading.
FEATURED STORY Currently, there are several lines other than the Port Liner which have unmanned automated driving. For example, Osaka Metro’s New Tram, the Yurikamome which runs along Tokyo’s waterfront area, The Nippori-Toneri Liner which is operated by Tokyo Metropolis, the Seaside Line which runs in the southern part of Yokohama City, and the Disney Resort Line which links the facilities at Tokyo Disney Resort.
Centre (OCC), from where teams of engineers track and monitor in real-time train movement across the DMRC network. The OCCs are akin to air traffic control towers equipped with large display walls and communication technology. DMRC has three OCCs, including two inside the metro headquarters and one at Shastri Park. But the level of control that the drivers or train operators have over trains vary from line to line.
All of these lines are elevated and their tracks are isolated from ordinary roads. Doors are installed on the platforms to prevent people from accidentally falling onto the tracks. People and vehicles rarely enter the tracks, there are no railroad crossings where accidents can easily occur, and they are well-protected from flying objects. For this reason, there is a distinctly low level of risk during unmanned driving.
From ATP and ATO, metro will switch to Driverless Train Operation (DTO) mode. In this mode, trains can be controlled entirely from the three command centres of the DMRC, without any human intervention. The Communication Based Train Control (CBTC) signalling technology also makes it possible to monitor and troubleshoot every aspect of train operations remotely. Manual intervention is required only in cases of hardware replacement.
The automated train of East Japan Railway Company’s (JR East’s) Yamanote Line, introduced above, is also the type that has a driver. The same is true of the automated driving that JR East plans to introduce on the Joban Line. Also, Kyushu Railway Company (JR Kyushu) conducted a running test of an autonomous train. According to reports, West Japan Railway Company (JR West) have also conducted a running test.
The author had a conversation with official and they said, "At the command centres, posts of information controllers have been created to handle the passenger information system, crowd monitoring. Rolling stock controllers will monitor train equipment in real-time, download faults and other events captured by CCTVs and assist traffic controllers in executing commands remotely".
The driverless train operation (DTO) or unattended train operation (UTO) modes can be implemented only on Line 7 and Line 8 of the DMRC network which came up under the Phase III expansion. These corridors are equipped with an advanced signalling technology which makes the transition possible. For now, DMRC is rolling out the UTO mode on Line 8 only. Although, the matter is very encouraging in the Indian context, even now, the trains are mostly remotely controlled from the command rooms of the DMRC known as Operations Control
Apart from this, all station controllers will also have access to onboard CCTV feed. But the system will still be one step away from the Unattended Train Operation (UTO) mode, the final stage of driverless services. The move is however being seen as one which will take away many jobs in a country where there is already scarcity of jobs as the youth population is much greater than any other nations of the world. Initially, the DMRC will have one attendant on the train. Until the DMRC switches to the UTO mode, it will have roving attendants, who will be trained metro operators, onboard to intervene in case of emergencies or other types of failures.
PM Modi Flagging off the India's First Driverless Train through Video Conference

FEATURED STORY During the virtual function, Prime Minister Narendra Modi said, “The inauguration of the first driverless metro train shows how fast India is moving towards smart systems.” “The first metro in the country was started with the efforts of Atal (Bihari Vajpayee) Ji. When our government was formed in 2014, only five cities had metro services and today 18 cities have metro rail service. By 2025, we will take this service to more than 25 cities”, he added. In metro systems, automation refers to the process by which responsibility for operation management of the trains is transferred from the driver to the train control system. There are various degrees of automation also known as the Grades of Automation. These are defined according to which basic functions of train operation are the responsibility of staff, and which are the responsibility of the system itself. For example, a Grade of Automation 0 would correspond to on-sight operation, like a tram running on street traffic. Grade of Automation 4 would refer to a system in which vehicles are run fully automatically without any operating staff onboard. The implementation of UTO systems allows operators to optimise the running time of trains, increasing the average speed of the system, shortening headways up to 75 seconds, and reducing dwell time in stations to 15 seconds.
capacity with the same (or even reduced) fleet size; the technical reserve (spare vehicles) can also be downsized. – Signalling and control systems – Full UTO represents a higher cost than traditional ATP systems. However, the current trend is to install CBTC systems on new lines – even with drivers (GoA2). The signalling technology is the same, the cost difference is marginal in the case of a new line. – Platform & track protection systems – The need to replace the role of the driver in preventing platform and track incidents represents the highest civil engineering cost increase. "Line conversion poses a more complicated business case. It is necessary to factor in extra costs due to the technical difficulties connected to the modification of the existing signalling and control systems and the need to replace or retrofit existing rolling stock, as well as the increased cost and complexity of installing platform and track protection systems in older stations. To minimise its impact, conversion projects should be timed to the end of the life cycle of the existing equipment", says an expert. "For conventional lines that upgrade to UTO in parallel with the renewal of rolling stock or signalling equipment, it is estimated that the return on investment period is around 10 years", he adds.
Greater flexibility in operation
When factoring in operational costs, automated lines come ahead of conventional lines; some studies indicate a halving in operational costs. Staff costs are greatly reduced which can be a negative aspect of the Indian perspective.
By taking the human factor out of the driving equation, operators gain flexibility and can make better use of assets. UTO systems offer a more tailored service coverage, reducing overcapacity supply at off-peak hours and enabling operators to inject trains in response to sudden surges in demand, for example in the case of big events.
One benefit of the system is that the acceleration and deceleration patterns can be adjusted to reduce energy consumption and maximise energy recovery, thus significantly reducing energy costs. While maintenance costs are marginally increased due to the introduction of platform and track protection systems.
Impressive safety records
Holistic efficiency and organisation opportunities
UTO systems also offer safer operations by reducing the humanrisk factor; well designed UTO systems have proven to be more reliable than conventional metros and hold an impressive safety record. Platform and track incidents aside, there has been only one operational incident in Osaka, at the end of the 80s, when a train did not stop at the terminus and hit a bumper stop, provoking injuries in a few dozen passengers.
Implementing UTO is being seen as a major milestone in the life of the operating Corporations. The introduction of a more sophisticated computerised system and Operation Control Centre (OCC) should be an opportunity to review most operation processes and assess how they can be improved and “plugged in” to the system in order to extract maximum benefit from the data process capabilities installed, and also yield better performance at optimised costs. The main operation areas likely to be affected are operation resource planning, staff training, rolling stock management, maintenance management, quality management.
Let's look at the benefits of the system which has been introduced in the DMRC network. These are as follows:-
Increase in quality of service Overall, passengers perceive an increased quality of service, thanks to the enhanced reliability of trains and shorter waiting times in platforms. The re-deployment of staff in stations also increases passenger’s level of subjective safety and security. Financial feasibility For new lines, automation costs will come at a relatively low comparative weight within the overall budget. Main cost factors are mainly connected to the rolling stock, the signalling and control systems and platform and track protection systems:-Rolling stock – An increase in commercial and average commercial speeds, reduced headways and the optimal distribution of reserve train sets along the lines translate in gains in the fleet. Thanks to higher reliability, it is possible to achieve more

Automatic Train Protection (ATP) is the system and all equipment responsible for basic safety; it avoids collisions, red signal overrunning and exceeding speed limits by applying brakes automatically. A line equipped with ATP corresponds (at least) to a GoA1. Automatic Train Operation (ATO) ensures partial or complete automatic train piloting and driverless functionalities. The ATO system performs all the functions of the driver, except for door closing. The driver only needs to close the doors, and if the way is clear, the train will automatically proceed to the next station. This corresponds to a GoA2. Many newer systems are completely computer-controlled; most systems still elect to maintain a driver, or a train attendant of some
FEATURED STORY
kind, to mitigate risks associated with failures or emergencies. This corresponds to a GoA3. Automatic Train Control (ATC) performs automatically normal signaller operations such as route setting and train regulation. The ATO and the ATC systems work together to maintain a train within a defined tolerance of its timetable. The combined system will marginally adjust operating parameters such as the ratio of power to coast when moving and station dwell time, to bring the train back to the timetable slot defined for it. There is no driver, and no staff assigned to accompany the train, corresponding to a GoA4. At Grade of Automation 4, ATC systems work within an overall signalling system with interlocking, automatic train supervision, track vacancy detection and communication functions. As of March 2018 there were more than 1,000 km of metro lines in Fully Automated Operation worldwide. These lines are running in 42 cities, becoming a common site among metro systems, with nearly a quarter having at least one automated line. This new Statistics Brief from UITP explores the characteristics of automated lines, analyses the growth of the past decade, and offers a perspective on the future of FAO lines. Chinese cities are set to power a tremendous growth in FAO, with an expected tripling of all the automated metro kilometres worldwide by 2022 if all confirmed projects advance according to plan. The European Scenario The first automated metro line in the European Union was launched in the French city of Lille in 1983. Initially, it consisted of 12 stations. Since that time, Lille Metro has been developed significantly. Now, it includes two fully automated lines with 60 stations. The technology for Automatic Train Operation (ATO) in
Lille is based on automatic rubber-tyred people movers. It was designed by French company Matra Transport International and also known as Véhicule Automatique Léger. Afterwards, this technology became popular in France. Besides Lille, the VAL solution was implemented in Paris (Orlyval service), Lyon, Toulouse and Rennes. In the 1990s Matra Transport International developed the communication-based train control technology for automated metro lines – Trainguard MT CBTC (now it belongs to Siemens Mobility). It was deployed in Lyon Metro (Line D) and Paris Metro (Line 1 and 4). Also, this solution was installed in other European countries including Germany (Nuremberg U-Bahn), Spain (Barcelona Metro) and Hungary (Line 4 of Budapest Metro). "During the next decade, Italian engineering company AnsaldoBreda (now Hitachi Rail Italy) has been developing its technology for automatic metro operation known as AnsaldoBreda Driverless Metro. Its other name is the Denmark Hitachi Rail Italy Driverless Metro due to the capital of Denmark as the first location of installation. Besides Denmark, it is popular in Italy, the company’s home market. Four Italian cities Milan, Rome, Brescia, Turin use this solution in their metro systems", says research. Since these trains operate on communication-based train control (signalling) system, they can be run with headway as high as 90 seconds to offer more carrying capacity. According to DMRC, initially, the train operator will be present on the driverless train to instil a sense of confidence and assistance for passengers. The driverless train operation's higher level of diagnostic features will help move from the conventional timebased maintenance to condition-based maintenance.

management and operations. In this manner, the technology is helping reverse the trend for rail transport to lose market share to other modes of transportation,” says an AI technology expert based in Dubai.
AI-powered smart trains AI technologies are already powering rail systems around the world. The Dubai International Airport, for instance, operates a fully autonomous train to transfer passengers from one terminal to another. It uses SelTrac, an automatic railway signalling technology from Toronto-based company Thales, to control the train autonomously. The Singapore Mass Rapid Transit Lines, currently the world’s longest automated metro system, is another case in point. This urban transit system has achieved Level 4 automation.
It’s another matter, altogether, that around three years back, India’s Union minister for road transport and highways, Nitin Gadkari, asserted that driverless cars will not be allowed in India because the government is not going to promote any technology that comes at the cost of jobs. However, the Automated Metro has been interested and it is very safe for passengers. Initially, an attendant is there in the Metro train to help the passengers in the case of any emergency. However, there are fears as the coming of fully automated technology in the other metro corporations will reduce human interference and thus the technology will become a cause for reduction of jobs. Although it has a negative aspect taking in point the job perspective it is a welcome move and we shall wait for a few years when the other metro corporations of the country start navigating with the new technology.
With the AI, a new era may start in the field of fully automated metro operations. It may even be greater than the present driverless systems where humans control the system sitting at control stations. A time can come soon when the need for human intervention will come to zero. “Today, we’re seeing AI being used in rail applications to improve train scheduling, manage train speeds, avoid accidents, predict delays, enhance asset management, and more. These AI applications help ensure public safety, deliver customer value, and optimize overall rail

ATMANIRBHAR BHARAT
India becomes Atmanirbhar in Head Hardened Rail Production
The Government must make Policies to curtail Rail Imports in a move to promote indigenous Rails and their Manufacturers Growing cities, growing population and growing traffic has invariably called for a shift from private modes of conveyance to public transport. India is looking to create a world-class infrastructure with its existent Kolkata, Delhi, Mumbai, Bengaluru, Hyderabad, Chennai, Jaipur, and Kochi metros with the addition of Pune, Chandigarh, Ahmedabad, Kanpur, Ludhiana, Bhopal, Indore, Agra, Kanpur and Faridabad are being chalked out. Metro Rail Tracks are designed to conform to the appropriate load category according to UIC Leaflet 700; axle-loads of coach and for a train speed of 90 kmph and shall enable a level of passenger comfort as per international standards throughout the service life of the rail system. Rails on Metro tracks suffer lateral and vertical wear due to load applied on rails by wheels. This is predominantly due to large traffic movement and sharp curves. In order to optimize utilization of rails for increase service life and reduce degradation due to wear and rolling contact fatigue, it is recommended to use Head Hardened Rails. Head Hardened Rails offers better service life and thereby rail replacement frequency from challenging underground and elevated viaduct sections is reduced. And hence Metro Projects are predominantly designed on Head Hardened Rails. Under the GOI ambitious “Make in India” scheme, the two large steel manufacturers in India took up the initiative to develop “Head Hardened Rails” to meet the growing demand of Metro Rail Corporations and High-Speed corridor projects indigenously.
However. it is seen that all Metro Rail Corporations and HighSpeed Rail projects are still insisting on imports of Head Hardened rails excusing lack in faith due to little or no experience of manufacturing by new Indian rail mills. Renowned Rail Track Expert and President of Rail Consult India, who worked in RDSO and was Additional Member Civil, Railway Board, Mr. J. S. Mundrey submits his concern over negligence of GOI policy and domestic capability by these projects. He further states that: “In India, we have now two Rail Rolling Mills, which have adopted “the state-of-the-art technology” in producing rails to National and International Specifications. But they could not participate in the rail tenders of Metro Rail Corporations and NCRTC as they were unable to meet the “Contractual and Technical Experience” prescribed in the tender documents. THE SUPPLY ORDER HAS THEREFORE BEEN PLACED ON AN OUT - SHORE COMPANY. Having worked in the Indian Railways for long years, out of that FOUR years in RDSO in the Track Modernisation Cell and FIVE years as Adviser Civil Engineering Railway Board, having written the book, ”Railway Track Engineering”, and presently engaged in Track Consultancy assignments, nationally and internationally, I can claim to have some knowledge of Railway Track Technology. I would thus submit, in all humility, as under for serious consideration. METRO RAIL NEWS | January 2020 | WWW.METRORAILNEWS.IN

ATMANIRBHAR BHARAT
Over half a century ago, when Indian Railways used to import all their rails, the stipulations of experience, as made in rail tender, was made as an additional safeguard to be sure about the capacity of the Rail Mills not known to us. Once Bhilai Rail Mill was established Indian Railways had no need to import rails. It is now since last few years that Metros started importing rails of the specifications not produced by Indian mills. Once the Indian Rail Mills have started producing such rails, fully meeting the technical requirements stipulated in Relevant Specification, asking them to meet the experience requirements is a negation of their right of supply of rails to their own National Railways. One can also ask as from where they can get experience when their own Railway System is reluctant to use their rails. 1. I would further submit that much water has flown through River Ganges, when the Experience Stipulations were made in the tender documents about HALF a Century ago, as brought out below.
INDIAN RAILWAYS THEMSELVES DO NOT CONSIDER THE NEED FOR ULTRASONIC TESTING OF RAILS FOR 25% Of THE STIPULATED SERVICE LIFE, WHICH MEANS SEVERAL YEARS IN TRACK. ONE YEAR TRIAL OF RAILS IS THEREFORE MEANINGLESS. In NUTSHELL I would therefore humbly suggest that: Once the rails have been manufactured by our own mills, strictly following the laid down specification, there is no need for asking for an experience certificate from them, as that only means to throw them out of the ring. One year trials of rails is a waste of resources as nothing can come out of such trials in the absence of well laid down parameters to be measured after the trial, and that is not possible for RAILS.
2. Rail making technology has undergone a sea change. Rails steel is coming through Concast route, with RH Degassing, completely eliminating the piping in the rails, a major cause of rail fractures. 3. Rail chemistry is well controlled. Hydrogen content in the rails produced by Indian Rail Mill is now less than 1.6 ppm, much below the international standards. 4. Modern cooling methods and the sophisticated rail straightening machines bring down the Residual Stresses to the bare minimum. 5. Ultrasonic Testing of full rails and Eddy Current Testing do not allow any defective rails to pass undetected. 6. With these developments, rails produced to the required specification, no certificate of experience is needed from the mill, and the rails produced by our Indian mills, can go straight to the track. 7. Inspection is done by RITES, that further assures the quality, durability and performance of rails. 8. It is doubtful if any World Class Railway System is demanding an experience certificate after the rails are produced to the laid down specification. 9. Field trials of rails for a period of 2-3 years show a lack of understanding of Rail Technology. The Track Engineers should know that field trials of only such track items is carried out, where certain specified parameters are evaluated after one year or so, to determine the deterioration behaviour, such as in elastic fastenings. 10.In Rails, when no such parameters are identified and measured, trials are meaningless. 11.Recently, trials for one year were undertaken by the rails supplied by an Indian Rail Mill. No manufacturing defects could be found, as expected, and rails produced by that mill have been cleared for general adoption. It has been a sheer waste of resources at various levels.

Hopefully, with this long narration of mine, there will be fresh thinking on the important issues of EXPERIENCE & TRIALS with respect to the rails produced by our own rail mills. This will be in the interest of NCRTC, Metro Rail Corporations, Indian Railways and the INDIA as a whole. Surely it will be furthering the cause of ATAM NIRBHAR BHARAT, much in line with the vision of our Prime Minister.

India to trial Hydrogen Fuel Cell Trainset
Indian Railways expects to roll-out a four-car hydrogen fuel cell multiple-unit by the end of 2021, as the country looks to alternative fuels as a way of reducing greenhouse gas emissions from the transport sector. * Bharti Jain is an electronics and communication engineer, who began her career in the telecommunications sector before joining Rites as a project manager for signalling & telecommunication projects. She is currently working on Indian Railways’ alternative energy initiatives and semi high speed rail projects. Next year will see the development of India’s first hydrogen-powered train, with a four-car demonstrator due to be rolled out of the Diesel Loco Modernisation Works in Patiala before the end of 2021. Mirroring initiatives in other parts of the world, the fuel cell powered multipleunit will be used to investigate the potential for decarbonising the rail sector, building on government plans to accelerate the use of hydrogen across the national economy. India has one of the fastest growing economies in the world, with the rapid expansion of heavy industries and other production. This has resulted in a significant increase in greenhouse gas emissions from both the industrial and transport sectors, notably carbon dioxide and carbon monoxide. According to a report by the Potsdam Institute for Climate Impact Research, India’s GHG emissions in 2015 stood at 3.6 million gigatonnes of CO2 equivalent, or about 7% of global emissions. That makes it the world’s third largest emitter of greenhouse gases. Climate change due to GHG emissions has been recognised as an increasingly important issue in recent years, with CO2 a major contributor. At present, roughly one-third of global CO2 emissions come from industries and a quarter from the transport sector. If current trends continue, by 2050 there would be a 55% increase in transport emissions, and 38% of global CO2 emissions would come from just seven industrial and transport sectors.

According to the International Transport Forum, global freight and passenger transport volumes are projected to grow three-fold by 2050. Demand is being driven by multiple factors such as economic globalisation, increasing population, urbanisation, tourism, rising international trade and the diversification of product value chains. More and more industries are moving away from manufacturing products at a single location, and expanding technology-specific production units which require the integration of components sourced from factories around the world.
METRO RAIL NEWS | January 2020 | WWW.METRORAILNEWS.IN
ARTICLE Hence the need to move both industry and transport to more sustainable forms of energy. To this end, rapid technological development and falling costs are helping to stimulate greater use of renewable energy sources. As part of its contribution to international efforts to limit the global temperature rise to 1·5°C, India is looking to achieve zero emissions from its heavy industry and transport sectors by around 2060. It has been working to reduce emissions from the transport sector through a range of initiatives. These include encouraging a shift from two-stroke to four-stroke internal combustion engines for road vehicles, the adoption of alternative fuels such as CNG or biofuels and the takeup of electric vehicles.
make hydrogen more economic than fossil fuels, where prices are predicted to rise as a result of restricted supply and government policies. Fuel cell manufacturing costs are also expected to fall, given that they are assembled from stacks of standard components. Hence, IR considers that hydrogen is likely to be the most promising technology for achieving a zero-emission railway network by 2030. Article continues below ↓ Fuel Cell Basics
In the rail sector, there are multiple alternatives for reducing carbon emissions, including biofuels, synthetic fuels, electrification and hydrogen. India has committed significant investment to accelerate the electrification of its national rail network, while the advent of a hydrogen-propelled train will provide a further weapon in the armoury for the fight against climate change.
Various types of fuel cell are now available, which are typically classified by the type of electrolyte used. They include Proton Exchange Membrane, Alkaline, Phosphoric Acid, Solid Oxide and Molten Carbonate fuel cells. Indian Railways has opted to use PEM technology in its hybrid trainset, because of the low operating temperature (50 to 100°C), short starting time and the ease of using ambient air as the oxidant.
Why Hydrogen? The Covid-19 pandemic has helped to underline more than ever the need to take sustainability seriously, and this has manifested into widespread enthusiasm for hydrogen as a commercial energy source. Between November 2019 and September 2020, India’s project pipeline for green hydrogen production has grown from 3·5 GW to just over 15 GW, signalling the emergence of a growing hydrogen economy. The Indian government is driving a number of initiatives to increase hydrogen production. The Ministry of New & Renewable Energy and major power generation players such as Indian Oil Corp Ltd and National Thermal Power Corp have committed to the establishment of hydrogen production units across the country and the implementation of fuel cell technology. Significant investment is envisaged by both public and private firms and the use of hydrogen is expected to expand between three- and 10-fold by 2050.
Each fuel cell transforms the chemical energy of hydrogen and oxygen to produce power. The electrodes (anode for hydrogen and cathode for oxygen) are separated by an electrolyte, which prevents the reactants from mixing directly and controls the charged ions created during the partial cell reactions. Hydrogen molecules enter the anode and react with a catalytic coating on the anode, releasing electrons to form a positively charged hydrogen ion. While the free electrons cannot pass through the electrolyte, the ions reach the cathode and flow into an electrical circuit, generating power. The cathode causes the hydrogen ions and free electrons to react with oxygen from the air to form water vapour. A single fuel cell under load produces between 0·6 V and 0·8 V, so multiple cells are stacked together to produce higher voltages.
In keeping with this trend, Indian Railways has begun to investigate the potential for hydrogen traction, as a cleaner fuel which is both convenient and cheap to obtain. Both battery and hydrogen trains have been considered as an alternative to diesel traction for operation on non-electrified routes. Conventional locomotives would need large and heavy batteries to operate over long distances or haul heavy payloads. Fuel cells offer a lower weight, better payload and a longer range. The consumption rate of hydrogen is less than diesel fuel, while the trains are quieter in operation. Unlike conventional diesel engines, hydrogen-fuelled trains emit only water vapour at the point of use. This results in minimum heat and low well-to-wheel . Given the right infrastructure, hydrogen is safe to handle and vehicles can be refuelled quickly, resulting in minimal downtime. Amongst the fuel variants, green hydrogen is considered to be the best alternative, being extracted from water using renewable energy such as solar or hydro power. This is preferable to ‘grey’ hydrogen produced by reforming fossil fuels or ‘blue’ hydrogen generated from natural gas. Given the rapidly expanding production pipeline and investment in renewable energy generation, the cost of green hydrogen is expected to fall by up to 65% between 2030 and 2040. This would
Global Development Internationally, countries such as Germany, Netherlands, France, South Korea, Japan and the UK are investing in the development of trains powered by hydrogen fuel cells as a part of their route to a carbon-neutral future.

ARTICLE when Alstom selected Hydrogenics as a key partner to develop the fuel cell technologies for its Coradia iLint project. The world’s first production fuel cell train has roof-mounted power modules and hydrogen storage tanks. During operation hydrogen is combined with oxygen drawn from the ambient air, in order to charge underfloor batteries which in turn power the electric traction motors. Unveiled at the InnoTrans 2016 trade fair in Berlin, Coradia iLint demonstrated a range of up to 1000 km between refuelling, and a similar performance to conventional diesel multiple-units, with lower noise and environmental impact. Two prototype units entered service in September 2018 for an 18 month trial on the Buxtehude – Bremervörde – Bremerhaven – Cuxhaven line in northern Germany. The units have also been demonstrated in other countries including Austria and the Netherlands, where tests were successfully conducted in March 2020. Alstom has so far received orders for 41 Coradia iLint trainsets. The first 14 are due to enter service in Niedersachsen during 2021, and the other 27 will be used in the Rhein-Main region from the end of 2022. In June 2019, the UK launched its HydroFlex demonstrator, developed by Porterbrook and the University of Birmingham, and this undertook its first main line trials in October 2020. HydroFlex has been created by fitting a fuel cell power pack to an existing Class 319 EMU, enabling it to run on electrified or non-electrified routes without modifying driver’s controls. Rolling stock leasing company Eversholt Rail is working with Alstom to develop a hydrogen multiple-unit to fit the restricted UK loading gauge; again using converted EMUs, the first Breeze trainset is expected to take to the rails in 2024. And in France, SNCF hopes to have its first fuel cell train in operation by 2022, with a view to eliminating diesel traction by 2035. Having been early in the field with its New Energy Train, East Japan Railway is looking to start testing its second hydrogen-powered trainset in 2021 at up to 100 km/h, with the first commercial version to be released by 2024. Korea Railroad Research Institute is also developing a fuel cell powered train for completion in 2022. This has been specified to achieve a range of 600 km on a single charge at a maximum speed of 110 kmph. Electrification is likely to remain the most effective strategy for reducing carbon emissions from heavy freight haulage. India’s Hydrogen Prototype Indian Railways has completed the design for a 300 kW fuel-cell-hybrid trainset rebuilt from an existing diesel-electric suburban multiple-unit. This will be assembled by the Diesel Loco Modernisation Works at Patiala in Punjab and is expected to be completed by the end of 2021. Modification of an existing train for hybrid operation is intended to speed development and minimise the manufacturing cost. According to IR, this will be the most powerful fuel cell trainset yet developed. As with many of the other hydrogen trains, it will have a maximum speed of 140 km/h. While the actual fuel cell power plant will be imported, the hydrogen storage system and lead acid battery packs will be supplied by Indian manufacturers. The four-car unit will have roof mounted lightweight storage cylinders on one vehicle to carry the compressed hydrogen.

The gas will be fed to the PEM fuel cells (left), which will be mounted on the roof. To avoid any loss of energy generated by the fuel cells, the train will be fitted with lead-acid batteries to store electricity produced during non-operational periods. The batteries will also capture regenerated braking energy, and help to smooth out the power demand under real-life driving conditions. DC-DC converters in the power vehicle will balance the voltage difference between the fuel cells and batteries. While the long-term intention is to use green hydrogen, the current plans envisage that the hybrid demonstrator would initially be powered using hydrogen obtained from industries which generate it as a by-product. In-House Hydrogen Production As well as investigating the use of fuel cells to power trains, IR is looking at the scope for developing its own hydrogen production systems, using water electrolysis powered by energy from renewable sources. There are currently two areas of investigation: nano materials and metal-oxide catalysts. The first would see nanoparticles fitted on existing solar cells, to mimic photosynthesis and separate hydrogen from water in the presence of sunlight. This approach has two key benefits. Firstly, it is a low-cost technology, and secondly it can work with seawater or wastewater, avoiding the potential wastage of clean water. The metal oxide method combines electrolysis with low-cost catalysts such as Spinel oxides to improve performance. Electrolysis is an established way to extract from water. Electricity is passed through water in an electrolyser, triggering two chemical reactions which produce hydrogen and oxygen. These two gases are then kept separate by a membrane. However, the oxygen revolution reaction is relatively sluggish, lowering the energy efficiency of the overall conversion. Spinel oxides are typically made of cheap transition metals and have been demonstrated as a stable, low-cost catalyst that could speed up the process and overcome the energy loss.
ARTICLE
IR is also experimenting with the production of ‘blue’ and ‘grey’ hydrogen from biogas or oil feedstock. Other Indian conglomerates now delving into green hydrogen production include NTPC and Tata Motors. Reliance Industries Ltd recently announced its intention to become a net carbon zero firm by 2030 by getting into green hydrogen production and
replacing its transport fuels with clean electricity and hydrogen. Indian companies are working to build a full-stack electrolyser and indigenous fuel cell solutions, combining the powers of d i g i t a l , p owe r e l e c t ro n i c s , a d va n c e d m a t e r i a l s a n d electrochemistry. Recently, FTI Consulting entered into an agreement with The Energy & Resources Institute to develop an India Hydrogen Economy Roadmap. This includes the deployment of grey, blue and green hydrogen, carbon capture and renewable energy technologies, as well as research programmes to test the viability of hydrogen as the sustainable fuel choice in an Indian context.

Flash-Butt welded Long Rolled Rails, LRR, of Prime Steel Quality help to lower the Risk of fatal Train Accidents in India
Rolling of Rail at British Steel Synopsis: Long Rolled Rails, LRR, of prime steel quality, already tested in the manufacturing plant, and with Flash-Butt Welds of higher strength than that of Alumino Thermic, AT, welds, provide far better alignment and continuity parameters for far smoother train runs, that lower the risk of in-service rail failures, which had led in past decades to nasty, unwanted and fatal train derailment accidents. The mutual impacts of rail and running wheel governed by Newton`s Laws of Motion are on tracks consisting of flash-butt welded long rolled rail panels far lower than on a track consisting of AT welded short 13 m rails. Long rolled and flash-butt welded rails are a prerequisite for 160 kmph Semi-High Speed Lines in India.

Mahakaushal Express Derailment near Kulpahar, 30.03.2017 In India, one thought, one could not keep rails longer than 13 m, otherwise the expansion gaps at the joints, hold together in position by bolted fish-plates, might become too wide; see J.S. Mundrey, Railway Track Engineering, 5th print edition, 2017, page 49, 103 ff and 329, McGraw Hill Education (India) Private Limited, Chennai, ISBN (13): 978- 93-5260-648-1 / ISBN (10): 93 -5260648-5. It had been considered that the gap between the rail ends should be proportional to the length of the rails to allow free expansion during hot weather.
ARTICLE The gaps between rail ends were generally thought to be the prime cause of impact at joints. Although the provision of longer rails would lead to a reduced number of joints, it was dis-favoured due to the increase of impact-density, if proportionately wider gaps were to be provided at the ends. To weld rails in long lengths was therefore technically disinteresting. It was realized later that the intensity of impact is not directly proportional to the width of the gap, and the gap itself must not be exactly proportional to the length of the rail because the rail does not really behave as a free rail when laid in track. With this realization any reduction in the number of joints was welcome, as it had the prospect to minimize, if not completely eliminate, the problems connected with the jointed track. With this background the welding of rails into 3 rails, 5 rails and 10 rails was started on Indian Railways. The welded panels have been named “Short Welded Rails” (SWR) as distinct from “ Long Welded Rails” (LWR). The experience with short welded rails has been that joints with panels of length more than 3 rails cause more damage to track than the proportional advantages derived from the elimination of joints. Welded rails panels longer than 3 rails are therefore no longer in use on the Indian rail tracks. Rails, welded into long strings of 200 m or more, denominated as LWR/CWR, behave differently at the joints and are governed by their own inbuilt system. On LWR/CWR track the expansion and shrinking forces get arrested over the frictions at the rail-seats, the rail-fastenings and sleepers in the track-bed. With the introduction of concrete sleepers and stronger track-bed structures efforts are made to have continuously welded track to the extent possible, as jointed track on concrete sleepers is beset with many maintenance problems including the structural failures of concrete sleepers at joints. Step by step the short 13 m panels, jointed by bolted fishplates, have been welded Alumino Thermic (AT) to LWR/CWR tracks.
ModernDigitalcontrolledAT“SmartWeld” HighQuality RailWelding by Th. Goldschmidt`s Digital controlled Process AT welding is the common conventional welding method, which enables rail to be manually welded in a relatively short time with simple devices at site. However, it is necessary to carefully control its quality at point of installation, in terms of both track component condition, assembly, rand the welding proceedure itself by well trained work forces. An good quality AT weld has a Fatigue Life of only about 56 % as compared to the parent rail, whereas a Flash-Butt Weld has a Fatigue Life of about 90 %. Japanese Gas Pressure Welds reach a Fatigue Life of 96%, however Gas Pressure Welding needs skilled work-forces and is only best suitable for stationary welding in factory or at site. See M.M. Agarwal, INDIAN RAILWAY TRACK ,twentieth edition, 2017,p.384, Prabha & Co. Delhi, India, ISBN 81900613-1-3. Often the AT welds on INR tracks are below standard and the Fatigue Life mostly below 56 %. This means, on an Indian LWR/CWR tracks consisting of AT welded 13 m rail panels, there are every 13 m weak spots and discontinuity/disturbance in rail strength and alignment parameters. INR tries to secure those weak spots with Joggle Fish Plates. The numerous Joggle Fish Plates on INR tracks reveal that INR is aware of the Risks of AT Weld Failures. To mitigate the impact of AT Weld Failures, which may lead to nasty fatal railway accidents, INR therefore tries to secure the AT welds with Joggle Fish Plates:

Kerr FUNDAMENTALS OF RAILWAY TRACK ENGINEERING, Simmons Boardman Book, USA, ISBN: 0-911 382-40- 2, 2003, p. 252. Newton`s FIRST LAW suggests that any change of velocity of a body under consideration must be associated with the counteraction of a resultant force, which acts on his body. This in turn suggests a relationship between the resultant force and the acceleration of the body. Newton assumed by his SECOND LAW the very simple relation that the resultant force, which acts on the body and causes acceleration, is linear related.
Finishing, Stripping and Grinding of AT Rail Weld
The THIRD LAW is the "LAW OF ACTION AND REACTION": “For every ACTION there is an equal and opposite REACTION”. This is probably the most famous law of motion. This means that if one object 1 acts a force out on another object 2 then object 2 will act the same size force in the opposite direction on object 1; F21 = F12. Here are diagrammes to visually show this:
“Action equals opposite Reaction”; F12 equals F21. Joggle Fishplate Rail Joint for INR from Chandra Industrial Works to secure AT Welds
To every Action or Force there is an equal and opposite Reaction or Force.
Securing Rail Fracture with temporary Joggle Fishplate In addition, the alignment of the welds are often inferior. On INR bends in the vertical and horizontal plane of AT welds are tolerated up to 0.7 mm, measured with a 1.5 m straight edge. For flash-butt welds a tolerance of max. 0.3 mm, measured with a 1.0 m straight edge, got stipulated. Poor alignments with discontinuities increase the lateral and vertical stress between running wheel/rail-vehicle and rail, governed by the Newton`s Law of Mechanics:

METRO RAIL NEWS | January 2020 | WWW.METRORAILNEWS.IN
ARTICLE In other words, when a body (rail-track) exerts a force on a second body (rail-vehicle), in consequence the second body (rail-vehicle) exerts a numerically equal but opposite force on the first body (rail-track).
Oscillating rail-vehicle movements, self-exited or exited by track alignment defects, like Shuttling, Lurching, Bouncing, Rolling, Pitching, Nosing and Hunting, increase further the deterioration rate of an already deteriorated track.
The force acted on the rail-vehicle causes acceleration in vertical and/or lateral direction and/or causes rotation movements. The extend of the acceleration and rotation is linear related to the force acted by the railtrack on the rail-vehicle and can be used to d e t e c t a n d m e a s u re r a i l t r a c k d e f e c t s b y m e a n s o f instruments/devices on board of the railvehicle (Instrumented Revenue Vehicle; IRV). The “IRV” can be a commercial and scheduled running Locomotive, Passenger Coach or Freight Wagon. See: F.A. Wingler: MONITORING INSTRUMENTS MOUNTED ON SCHEDULED RUNNING COMMERCIAL TRAINS (INSTRUMENTED REVENUE VEHICLES, IRV) MAKE USE OF NEWTON`S LAWS OF MECHANICS FOR TRAIN BASED AND INSERVICE TRACK-CONDITION MONITORING IN TARGET PLANING OF MAINTENANCE; published on: May 18, 2018; http://www.drwingler.com .
At misaligned and un-straight rail-joints and rail-welds as well by wheels running with flat spots, high impacts are caused. Latter produce high rail and rail-weld bending stress, causing degradation of rail-welds, rails, rail-fastening systems, sleepers, ballast and track substructure components.
The Railway is a system, where steel-wheels run on steel-rails with a non-elastic contact area of less than 3 cm². This means that track and train interact over a contact area of less than 3 cm², and wheels exert the forces over this small contact area following Newton`s Laws of Mechanics:
The geometrically perfect production of welded rail-joints and the correct alignment and rail-surface profiling of the jointed rails are therefore essential parameters for the durability of the welded joints. Rail-straightness and even rail-surfaces of welded joints are decisive factors for the durability of welds. A passenger travelling in a coach on Indian Railway`s tracks can detect nearly each and every rail-weld by the “tack-tack ” sound, caused by the response of the wheels, when running over un-straight and/or uneven railwelds. In countries of advanced railways with perfected welded rail-joints, such sound is not audible. There is a clear correlation between weld-shape and the corresponding vehicle dynamics, which can be monitored by IRV. In-service rail- and weld failures are in India frequent and have caused many derailment-disasters with high mortality rates:
Wheel-on-Rail Contact Area of new Wheel-Treat and RailHead Profile on straight Run When running on a straight rail-track, on a perfect aligned and smooth rail-table without any roughness and with only little raildeflection under the wheel load (optimum in the range of 1.5 mm), there are only little additional vertical and lateral inter-acting forces causing acceleration, deceleration and rotation on the railvehicle with equal corresponding forces acting on the rails. That is, why a high quality rail-track experience only little additional corresponding forces of the running railvehicles acting on the rails. Therefore, a high quality rail-track keeps its properties under given traffic load, volume and velocity over a longer period and loses its properties over the time with a slower deterioration rate. The deterioration rate under given traffic load and train speed is an index for track quality. On poor quality rail-tracks of bad alignment and poor bearing capacity with tract defects like, kinks, dips, undulations, twists, high raildeflections under wheel load (related to deteriorated track components/constituents, poor bearing sub-structure components and poor drainage), rail-table defects and roughness (corrugation, rail-headburns, RCF), running vehicles experience high additional vertical, lateral and rotation forces exerting equal opposite forces on the rail-track damaging the track components. With increased speed and accumulation of traffic, through this mutual “ SELF-DESTROYING SYSTEM” the situation can deteriorate rapidly.

CHALLENGE TO IMPROVE EXISTING RAIL TRACKS CONSISTING OF SHORT 13 m AT WELDED WITH LRR RAILS OF PRIME STEEL QUALITY The challenge is to replace on old lines all rails consisting of short 13 m rails of insufficient rail steel quality and poor quality AT welds, which are in need of joggle fish-plates, by Flash-Butt welded long rolled rail panels of prime steel quality. Another challenge is the proactive and corrective Rail Management Strategy under a comprehensive Friction Management by ultra sound testing and by frequent rail grinding and milling, to prevent surface cracks to penetrate into the rail head leading to rail fractures. Long Rolled Rails, LRR, of prime steel quality, already tested in the manufacturing plant, and with Flash-Butt Welds of higher strength than that of AT welds, provide far better alignment and continuity parameters for far smoother train runs, that lower the risk of in-service rail failures, which had led in past decades to nasty, unwanted and fatal train derailment accidents. The mutual impacts of rail and running wheel governed by Newton`s Laws of Motion are on tracks consisting of flash-butt welded long rolled rail panels far lower than on tracks consisting of AT welded short 13 m rails. Long rolled and flash-butt welded rails are a prerequisite for 160 kmph SemiHigh Speed Lines in India.

Better knowledge about rails in INR will help for better information based planning, actions and decisions at the right place and at the right time in order to bring down the frequency and prevalence of in-service Failures of Rails and Rail Welds, one of the root courses of so many unwanted, nasty and fatal train accidents in India.

PROJECT OF THE MONTH
Nagpur Broad Gauge Metro Nagpur Broad Gauge Metro is a suburban rail (Commuter Rail) project planned for the city of Nagpur and extending up to adjacent districts of Wardha, Narkhed, Ramtek and Bhandara (also Nagbhid in the near future) in Vidarbha region of Maharashtra, India. This project will be executed by Maharashtra Metro Rail Corporation Limited. The distance and number of stations on these 4 lines and 268.63 km long project are:- Wardha (78.8 km, 11 stations), Bhandara Road (59.2 km, 9 stations), Ramtek – (41.6 km, 6 stations) and Narkhed (85.5 km, 10 stations). The travel time is Wardha – 1 hour 10 min, Narkhed – 1 hour 15 min, Ramtek – 1 hour and Bhandara Road – 55 minutes. The cost of Metro tickets will be 1.38 times the railway fare. The trains will travel at a speed of 120 kmph and reduce travel time by half. The project will now be submitted to the central government for sanction. The project was the brainchild of Union transport minister Nitin Gadkari. The international funding agency – KfW – which has funded MahaMetro’s Phase I project, has agreed to finance BG Metro project to the tune of ₹ 305.20 crores of the total project cost of ₹333.60 Crore. Of the balance, the state government would also provide 50% of the Strategic Debt (SD) of the Government of India (₹ 7.10 crore) and 100% (₹14.20 crore) of SD incurred by the state government. Thus collectively, an amount of ₹21.30 crore would be sanctioned by the state government. Rest will be borne by the Central government. The project was first proposed in 2018, and the memorandum of understanding (MoU) between Indian Railways, Government of Maharashtra & MahaMetro was signed in July 2018.

YEAR REVIEW
A u t h o r e d B y. .
Priyanka Sahu Director, Business Development Symbroj Media Pvt Ltd
Year 2020 at a Glance The year started with the onset of the Covid-19 pandemic and it modified the ways which we used to live in. The scenerio changed in India in the second week of March and then after the country went into full lockdown since March 24, 2020 and few sectors remain under partial lockdown even now. The year was really very challenging and it indeed threatened the very concept of the human life.
The year also saw the construction works of metro projects getting started in new cities like Agra and gaining pace in Kanpur. The water metro project of Kochi also gained momentum in the year. The most awaited RRTS project was initiated, the design of its rolling stock was launched and the works for the first RRTS Corridor of the country got started. Bombardier's new rolling stock and TBMs have been a matter of attraction.
As the pandemic hit the world in the initial days of the year 2020, the things became out of control in some nations. 1.98 million people have already died worldwide due to the Coronavirus Pandemic. The seriousness of the pandemic has been experienced by all of us and I think that the sanitizers and masks will continue to be an essential item of our daily lives for few more years.
The Bullet Train Project has also gained momentum with major tenders for civil construction works being awarded to companies. L&T emerged as a major player in the bidding process of Bullet Train Project and these all things will give a boost to the first HighSpeed Rail Corridor of the country.
However, at the end of the year, the vaccine was invented and its use was approved by different nations. The rigorous scientific research has yielded its fruits and it has shown a more humanitarian path to the mankind. We as a nation have been overcoming the problems created by the pandemic and I hope the things will be normal in the next few months.
Coming to the Metro and Rail Sectors, it wasn't a good year at all for the operational part. However, it has been a wonderful year when it comes to development of new projects. The new metro projects are coming up very fast and they have achieved new heights even during the pandemic. The year saw the opening up of 31 km long new metro lines for public in the year. These lines came up in Nagpur, Kolkata, Hyderabad, Jaipur and Kochi. With all these developments, we have now 678 km of operational metro corridors in the country while 485 km of metro lines are under construction process. The distance of proposed Metro lines has reached to 1041 km while 515 km of metro routes have been approved by the government.
With these all developments, we have finally got our first HighSpeed Rail Corridor and Semi High Speed Rail Corridor in the year 2020. At the end of the year, the first driverless train of the country was unveiled by PM Modi which is currently operating on the magenta line of the DMRC network. The DMRC turned 18 in the year 2020 which is really a matter of pride for the country. India has stepped into a phase where it is laying the foundation stone for a Next-Gen urban transit system and the last year of the second decade of this century witnessed this development. "The inauguration of the first driverless metro train shows how fast India is moving towards smart systems", the PM said while unveiling the first driverless train through his virtual presence. The things were better than ever for the Metro and Rail Sectors and we are hopeful that the new year brings more fruitful results. We encourage your participation and therefore we request you to continue your support during this year in a more peculiar way. We are starting a program where we will publish an article from readers or based on your suggestions. We thank You for the support which you provided in the year 2020. Thanks
