Mumbai High-Speed Rail For the proposed Nagpur Mumbai HighSpeed Railway, the Railways Board is weighing the option of a Samruddhi Corridor alignment, Whose DPR is being made by the National High-Speed Rail Corporation Limited.

The project is facing some issues including the land acquisition for the proposed high-speed rail track, as per the senior railway officer.

“It will be too quick to comment on how the HSR would move through the Mumbai – Nashik – Nagpur route. There is a Greenfield project in one of the proposals being weighed. The lands prepared with the Samruddhi Corridor cannot be ruled Out,” declared the officer. The stateowned National High-Speed Rail Corporation Limited that is also looking after the construction work of the Mumbai–Ahmedabad HSR service, commonly denoted as the bullet train, has been assigned the responsibility of preparing the DPR and the exercise is possible to take about a year’s around time. Further, the officer pointed out that a survey will be 1st carried out to settle the best route among the two cities. “Since this would be a high-speed corridor, where trains will run with speeds exceeding Two-hundred kmph, the existing alignment is of no use. That can best serve semi-high speed trains running in speeds in the range of 50 kmph-180 kmph. Hence we have to go for new alignments,” the officer responded.

ARTICLESTORY COVER Tunneling Technologies Driven by Evolving Construction Methods

T

unneling construction obtained speedy momentum in India during the past decade. Metro railway projects across the country widely showcase varied technological requirements for tunneling. DMRC has always been a forerunner i n a n a d a pt i o n of a d va n ce d t u n n e l i n g co n s t r u c t i o n methodologies based on project requirements. Kolkata Metro Railway's underwater first metro tunnel will also add new dimensions for tunneling construction. Following completion, the 33.5 km long line with 26 underground and one at-grade station will be the first underground metro line in Mumbai. Evolution of newer construction methods and supporting technological requirements has extensively resulted in the creation of newer b u s i n e s s o p p o r t u n i t i e s fo r t h e t u n n e l i n g m a c h i n e r y manufacturers in India.

Into account thickly vegetated, inaccessible terrains, rock formations, small and big shear zones/thrusts, and hydrological conditions at the site. Tunnelling in such places can often pose the threat of face collapse, chimney formation, water-inrush, hot water springs, gas explosion, squeezing and so on. Manufacturers of tunnel boring machines (TBMs), drilling equipment and so on must adapt their machines to the required design and engineering in the project, while meeting the safety standards and progress timelines. The Tunnelling equipment must also be backed by strong technical support by the manufacturers, with regular performance monitoring and troubleshooting.

Drilling Accuracy Quality tunnelling demands reducing over break, arresting damage to the surrounding rock and achieving better blast efficiency. One of the essential requirement for achieving the three things is accuracy in blast hole drilling. Atlas Copco has been making product enhancements in its medium, large and extralarge, face drilling rigs, branded as Boomer.

Construction Methods & Technologies There are various methods of tunneling. The selection of methods depends upon the size of the bore, the conditions of the ground, the equipment available, and the extent to which timbering is required. Above all, costs and project completion schedule are also major determinants towards selection of the methods and te c h n o l o g y. Not to m e nt i o n , e m e rg i n g co n s t r u c t i o n requirements, precisely those taking place in urban areas with high population and vehicular concentration is an added significant yardstick behind the selection process. The most modern methods being adapted in India for tunneling is Tunnel Boring Machines (TBM). The other method with supporting technologies being used in different situations include drilling and blasting, Cut and cover method, forepoling, linear plate method, New Austrian Tunneling Method (NATM), Belgian methods, shield tunneling etc.

Tunnelling Technologies & product support keep pace with construction complexities.

Advanced technologies, mechanisation of equipment with heightened safety features, and timely service and technical support to end-users can help the construction industry deal with construction complexities and pre-empt risks in different geologies and in hostile project sites. P.P. Basistha traces the latest d eve l o p m e nt s a n d s t rate g i e s of l e a d i n g e q u i p m e nt manufacturers in meeting tunnel construction requirements of the contractors.

There is a series of the metro, road and rail tunnels, water and sewerage projects lined up for development across the country, with close to 2,750 km of tunnel projects at various construction stages. Each project must contend with its own set of challenges posed by the geological terrain, some of which can be complex and critical in nature.

Since tunnelling is a highly cost-intensive job, it requires timely progress, which is monitored by the project developers. For construction companies, the challenge lies in adopting various construction methodologies that achieve faster and better productivity, with very high levels of safety, while keeping operation costs low, and attaining the total lifecycle cost of the equipment. Tunnelling is risky in soils that are relatively younger, and through fragile, weak and jointed rock masses of the Himalayan region, in the Pleistocene area, Deccan Trap, Gondwana, Vindhwan, and other alluvium and pre-Cambrian geologies. The risk is also high in almost all the seismic zones of India. According to the construction major, planners, designers, engineers, geologists, and construction contractors have to take

Debabrata Sain, Marketing Manager-Underground Rock Excavation, Atlas Copco India, says, “The Boomers come with various automation levels, for hole accuracy, accurate depth drilling, measure while drilling, telematics and round log report.

Atlas Copco Face Drills are now in fifth generation of Rig Control System (RCS) with more robust components for aggressive environment and demanding situation.” He continues, “Easy access to information is a prerequisite for tunnelling and mining engineers to help them produce a tunnel or a drift that matches the planner’s original design. With Underground Manager intelligent system from Atlas Copco, all of this information is now readily available and is more advanced than its earlier Tunnel Manager.”

ARTICLESTORY COVER Mr. Sain adds, “Underground Manager (UM) brings together the planning and administration of drilling and blasting into one simple tool. Its primary function is to generate drill plans that enable the rig operator to position drill holes correctly, create log files showing where the drill holes have been placed and provide information for navigating and positioning. It does this by enabling drill plans created in the mine or site office to be seamlessly transferred to the drill rigs, either on a USB memory stick or via local area networks. In addition, thanks to the RCS control system installed on all of our computerized equipment, the system is fully integrated with a broad range of useful functions such as Tunnel Profiler and Measure While Drilling (MWD). This means that UM will capture all of the log files, including the scans produced by Tunnel Profiler, and reproduce them as reports. The second upgrade allows the full integration and administration of charging and firing plans. This enables drill plans to be generated showing how the hole is to be charged and exactly when it will be fired. In addition, any changes that are made, are automatically updated and synchronized with all other information in the system. This is also a great advantage. By selecting designated sections and using the UM’s drawing tool, various firing scenarios can be tried and tested with blast hole sections given individual delay times, according to a chosen sequence. This ensures that the right firing sequence is employed.” He elaborates, “The small and medium rigs are equipped with (upto) two booms, covering cross sections from 6 m2 to 85 m2. We offer rigs with our Direct Control System (DCS) or with computerized Rig Control System (RCS), to which different levels of automation may be added. An extensive range of rock drills is available from 16 kW to 30 kW of impact power.” Atlas Copco offers Boomer L2D, Boomer 282, Boomer S1D, and Boomer XE3C Jumbo drills for the Indian market. Our rock bolting rigs used in mining and tunnelling are suitable for roof heights between 1.611 meters. Features include a screen handling arm for installation of wire mesh, RCS system for positioning drilling and bolting, and Cop 1132 and Cop 1435 hydraulic rock drills especially designed for bolt hole drilling. Other features are automatic resin injection, automatic cement system, bolt plan navigation and lift and tilt cabin.” Mentions Mr. Sain.

Sandvik has unveiled its new ‘i-series’ or intelligent series of jumbo drills, long back in western market and the technology is being introduced in India as well. The computer-controlled DTi series tunnelling jumbos are designed to be fast, accurate and userfriendly, delivering high-quality excavation results at optimum costs. The series is available in different models for excavation of cross sections 12–232 m², including face drilling, bolt hole drilling, and mechanized long-hole drilling. “This is a revolutionary product in its class, combining power with precision,” says Mr. Prabhat Mittal-Business Line Manager, Underground Drilling (Tunnelling), Sandvik India.

METRO RAIL NEWS | APRIL 2020 | WWW.METRORAILNEWS.IN

He adds, “In conventional jumbo drills, the operator undertakes the varied functions, based on his assessment and skillsets. This can lead to inaccuracies due to possible deviation in drilling and other related jobs, causing an improper tunnel profile and not in accordance with the project specifications. This can result in time and cost overruns, and of course, can impact safety. With the new intelligent jumbo drills, accurate hole placement, optimal profiling increases that further minimises the overbreaks. Sandvik’s ‘iSURE’ software improves the planning part significantly and offers an overview of the actual drilling process. iSURE gives specific guidance for different stages of drilling and blasting, keeping project costs low, and guaranteeing smooth proceeding of the tunnelling work thus helps in optimizing the drilling and blasting patterns. Sandvik iSURE and the new generation intelligent DTi series jumbos (like DT921i, DT922i, DT1121i, DT1131i, DT1231i, DT1331i) together form an unbeatably accurate rock excavation system for tunnelling and underground spaces. I-Series jumbos comes from our factory in Finland along with some other conventional drill models suitable for Indian market. Sandvik has a dedicated training facility in Nagpur and a refurbishment centre-cumworkshop that renders aftermarket and maintenance support to key customers.

Surface Stabilization Advancements Quality shotcrete is gaining prominence in Indian Tunnelling industry, thanks to demand from construction consultants that are following modern tunnelling methods. Shotcrete becomes an inseparable part of all modern tunnelling methods being adopted in Himalayas as the same is integral to the support system.

Machines that are technologically advanced and focus on precision machines are gaining prominence over low quality equipment. “Atlas Copco caters to Indian market in two categories- MEYCO ME3 of 20 cum/hr capacity and MEYCO ME5 of 30 cum/hr capacity. Our machines feature all pre-requisites of a shotcrete machine, namely, a shotcrete pump with S-Valve technology controlled through PLC circuit, an accurate PLC assisted dozing circuit for a dozing accuracy of ±2% and the strongest boom in the segment. MEYCO manipulator coupled with MEYCO shotcrete pump ensures minimum shotcrete rebound and desired strength, matching consultant’s requirement of early strength and final strength,” says Mr. Sain. He adds, “Consumers of Atlas Copco MEYCO products are realising the difference between a concrete pump and shotcrete pump.”

Normet India has recently launched its new low pulsation,Spraymec 5100 VCWET Shotcrete machine for the Indian market. The tunnelling equipment conglomerate, which is importing the product from its parent facility in Finland, has delivered six units to different tunnelling projects in the country such as the AMR Irrigation project in Andhra Pradesh and North Frontier Railway. Contractors namely Coastal Engineering and ABC Infrastructure have also acquired Spraymec 5100 VC for their Tunnelling Projects.

ARTICLESTORY COVER Sharing details, Mr. Milon Mukhopadhyay, Management Advisor, Normet India Pvt. Ltd., says, “Spraymec 5100 VC is an advance mobile concrete sprayer for modern tunnelling and mining operations in small and medium sized tunnels. It is an ideal solution for EQ and for NATM tunnelling. Spraymec 5100 is operated with electro hydraulic power pack. It features Normet’s NSP 30 advanced concrete spraying pump with maximum theoretical concrete output of 28 cum/hr. Electrically driven FAD 10 cum/min/7bar (55kw) screw type compressor ensures reliable air supply for spraying. NSP 30, which is a low wear and low maintenance double piston pump, has a high pumping pressure, which enables proper conveying of wet shotcrete mix. It can pump upto aggregates size of 16 mm, for plain shotcrete and for SFRS including fibres with maximum length of 60 mm in the concrete mix.

He adds, “The accelerator dosing system Nordoser XE in 5100 VC comes with mono style pump and accelerator. The accelerator dosing is synchronised automatically with concrete output, which is controlled electronically by remote control. Nordoser is available with optional low pulsating Normet peristaltic dosing pump Normet LPP-D with additional process information display in cabin. The advanced Normet spraying boom SB 508 D in 5100 VC ensures good reach and reliable operation in small and medium size tunnel profiles. The boom can deliver automatic functions involving vertical and horizontal stabilization, nozzle rotation, and telescopic stroke. For longevity, the upper boom telescope is protected with a heavy-duty, wear-resistant cover.

The speed of the movements cab is adjusted from the cabin display, and all the proportional movements are pressure compensated and have proportional output. Added feature of the equipment is the remote-control system for dosing rates, accelerator pump operations, concrete pumping speed, and wall washing cab, all of which can be adjusted from the control box.”

Another new product recently launched from Normet in India is the Spraymec 1430, truck mounted WET shotcrete unit, which was delivered to a recent road tunnelling project in Himachal Pradesh. Normet will soon be offering a dry shotcrete unit from Meyco for slope stabilisation. Dry concrete spraying business from Meyco was acquired by Normet recently, following which, the company will be offering dry shotcrete machines and its own wet shotcrete equipment.

Of our concrete sprayer is its flexible spray nozzle, which can be rotated 360 degrees for better and more uniform concrete spread. The core pump is made in-house, which ensures consistent productivity, supply and serviceability. The sprayer has a separate in-built system for additive mixtures,” informs Mr. Parminder Gabri, Head of Sales at Putzmeister India.

Putzmeister is targeting hydro and road tunnels for its shotcreting solutions, which were used in the recently completed Chenani Nashri link road tunnel project. The products are being marketed and supported through Putzmeister India’s own distribution channels.

Geological complexities & dimensional challenges There is an emerging demand for compact TBMs for use in constricted areas such as metro projects coming up in urban areas which have diameters shaft restriction for launching and evacuation. This requires design customization as per the project, such that the type and arrangement of the cutting head can meet the requirement of the site. Since the diameter of the TBM must be equal to the diameter of the designed tunnel, including its lining, the machine has to be customised accordingly both for ease of launching and functioning.

Also widening its product category is Putzmeister India, which is now offering shotcreting solutions as well. Among others, the German concrete pumping solutions major is marketing SPM 4210 PC and SPM 500 PC concrete sprayers for the Indian Tunneling Construction sector. The products are being imported from Putzmeister’s facility in Spain, however, the company is also working on indigenizing them at its Goa facility. “A unique feature METRO RAIL NEWS | APRIL 2020 | WWW.METRORAILNEWS.IN

ARTICLESTORY COVER According to Mr Kapil Bhati, MD, Robbins India, “Based on the project geological strata requirements, Robbins offers a wide variety of TBMs categorized separately in hard rock TBMs and soft soil type. Common type of hard rock machines are open grippers or main beam TBMs, single shield and double shield TBMs, soft soil or EPB’s can be soft soil EPBMs, mixed face EPBMs and Crossover/Hybrid EPBM’s .Robbins manufactures its own cutters and conveyors to support the requirement of project till its completion. Robbins also provides support equipment’s like rolling stocks for the muck disposal as an optional requirement for the contractors. Robbins Crossover TBMs have bidirectional cutter-head with the maximum thrust and torque thereby making them most powerful and robust for rock/mixed face geology.” Sharing further details, he continues, “Our Latest offering is ‘Crossover’ XRE series of TBMs. This dual mode Crossover machine with centre screw has been successfully used in Australia’s Grosvenor decline tunnel, where it excavated two coal mines access drives 14 times faster than traditional road headers. The same series of machine has been successfully used in hydro power project in Turkey. Robbins can customize the Crossover series as per the requirement of the project and geology and can make XRE (Crossover Rock/EPBM), XRS (Crossover Rock/Slurry ) and XSE (Crossover Slurry/EPBM) which are ideal for mixed ground conditions that might require multiple tunnelling drives .XRE is the most efficient type hybrid machine with characteristics of Single shield hard rock TBM and EPBM for efficient excavations in mixed soils with Rock.”

Mr Bhati points out, “ Since, there is not sufficient data available before the tendering process commences. We understand regarding the areas which has the limitations like Himalayas wherein the cover above the Tunnel is as high as 1000m to 2000m. On the other hand, certain water transfer tunnel project have no accessibility due to the wild life sanctuaries and other constraints and metro projects have less accessibility of lands in urban areas which does not allow the clients to perform proper geographical mapping which results in award of tender to the contractor with limited geological information. Contractor in turn have to gather that information by themselves which takes time therefore delaying the project and losing more time. Better and earlier information on geological details allows the manufacturers to design the machines and give them provisions to equip the machine to encounter any problems that may occur while excavation. Conceding that the TBM are cost intensive and it is vital that the life cycle costs of the equipment should be below the capital investment cost. Mr Bhati Says,” Robbins TBM’s are designed in view to be used in several projects thereby the lifecycle of Robbins product are far more than others as the same machine of any type can be used in multiple projects thereby

Reducing the burden of capital investment on a single project.

Our machines also uses lesser consumables which makes them cost effective to own and operate throughout the duration of the contract. HCC had deployed a Robbins 10-meter, double shield TBM for constructing a 19.2 km tunnel for Pula Subbaiah Veligonda irrigation channel in Andhra Pradesh. The continuous lining behind the machine has 300-mm thick concrete segments in 6+1 arrangement, making the finished tunnel diameter 9.2 meters. The tunnel path was through sedimentary rock and several faults and folds with some ground water. A probe drill mounted on the machine enabled verification of the geology 30 meters ahead of the TBM. A strict programme of probe drilling along with adequate ground stabilization allowed the TBM to advance through the difficult sections of rock.

HCC had also deployed Robbins TBMs for the smallest and largest diameter tunnels under Brihanmumbai Municipal Corporation.

German TBM manufacturer, Herrenknecht offers TBMs with diameters up to 19 meter diameter. Mr. Nitin Garg, Director, Business Development, Herrenknecht India Says. “We offer a full range of TBMs and associated equipment for tunneling in various geologies ranging from soft ground, to mixed ground or hard rock conditions. Herrenknecht Mixshield technology, is an improved version of a conventional slurry TBM, in which face support pressure can be controlled more precisely.

Our TBM’s facilitate change of tools in case of wear or damage from inside the machine.” Herrenknecht TBMs have been used in various Metro projects in India such as all 3 phases of Delhi Metro, Chennai, Bangalore, and Kolkata Metro in addition to few irrigation projects in India. Mentioning further he says, “Cutterhead designs including tool configurations in our TBMs are generally customized for geological conditions.

This is based on anticipation of the project followed by due study of geology, our past experiences. Not to mention, our extensive involvement with the projects at an early stage.” For the 2.74 km long sewage tunnel with a finished diameter of 2.5 m, HCC used a shield TBM lined with precast concrete segments for boring.

Tunnelling challenges included massive and weathered basalt, and the groundwater level along the tunnel alignment. A Herrenknecht hard rock TBM of 3.065-m diameter with integral automatic grout injection system was used. According to HCC, for the first time in India, a shielded hard rock TBM and gasketed linings were used for a project.

TBM Refurbishment, Service & Parts Support Robbins will soon setup a new refurbishment /Assembly centre near Mumbai in India which will provide service support to the machines through its crew of 200 engineers including 30 experts expatriates whose expertise can make the machines work even in most difficult geologies.

ARTICLESTORY COVER

“One way of reducing risk, is to have the TBM manufacturer support the project through its execution, not just at the beginning or limited to the supply of machines. Most of the time delays are because manufacturers due to not fully involved with the project and the contractor has limitations of coping with the difficult geology. On most of the projects where Robbins machines are deployed, we are involved intensively on the project by providing full support with crew /spare parts of TBM, cutters for execution and even operating on per meter basis. The risk of low progress due to adverse geology is absorbed and taken care

by Robbins.” Mentions Mr. Bhati.

Sharing details of the company’s strategy of offering complete product support, Mr. Bhati says, “Our comprehensive product support has been particularly important to the Bangalore metro for which delays have been widely reported in the local media.

Robbins was approached by the contractor and BMRCL to take over the balance contract execution due to constraints of delays on the job. As result Robbins supplied a crew of experienced people along with materials and took over the task to complete two tunnel drives of 750m each from Chickpet to majestic station.Both the drives were successfully completed in the stipulated time frame. The problems encountered inside the tunnel were that ground was challenging with very hard rock into mixed face and soft ground. The geology was challenging as there were uncharted wells, cavities and old buildings/stockyards above the alignment of the tunnel. The design of the competitor’s machine was not robust to tackle such geology resulting in very low penetration rates thereby low advance rates. However, with our extensive knowledge base for product support we could overcome the hurdle and made the equipments fully functional.”

Herrenknecht India has a skilled team of engineers, technicians and tunnel engineers to which help customers to succeed on challenging projects. Herrenknecht India has a large facility in Chennai which employs a team over 100 experienced technicians from India and abroad for 24/7 site support. “Our Chennai facility also specializes in TBM refurbishment / upgradation to suit new project requirements, cutting tool manufacture as well as centralized supply of spare parts. Herrenknecht Chennai facility exports parts, cutting tools as well as fully assembled TBM’s to various projects in Asia and Europe,” says Mr. Garg.

He informs, “Herrenknecht is the only TBM company having its own workshop for OEM refurbishment of TBMs in India. This becomes increasingly important as OEM refurbishment is a mandatory tender requirement on many projects in the country.”

Good quality spare parts for TBMs, backed by technical support from vendors, through co- engineering with TBM manufacturers, especially for installation and replacements are equally important for the machines to achieve high advanced rates in hostile site conditions.

Gates India undertook a major refurbishment of TBMs working at major hydro power projects in India. Mr. Rajesh Bhandari, MD, Gates India, says, “Given our high level of R&D competence, we can technically support OEMs and end-customers by improving the routing of the hoses and suggesting right hose for the application for more efficient performance. We can undertake monitoring and analysis of the hoses and couplings in the TBMs at varied geological conditions. We can also service other tunneling equipment like underground loaders, and for rigid and articulated dump trucks working at extreme temperatures in tunnel projects.”

He adds, “Safety and durability of the hoses and couplers in TBMs will help in delivering the required progression rates. Damage to the hoses can occur from falling rocks, and they must also be flame resistant when working under high temperatures. We have hoses that are 4 to 100 times more abrasion resistance; they contribute towards the total lifecycle costs of the TBMs and drilling and shotcreting equipment. Our Mega Crimp couplings are shorter in length and do not shear off with rock falling on them.

The hoses and couplers are manufactured as per Gates’s tested ‘Stamped’ product development strategy, which takes into accountthe required size of the hoses, ambient temperatures, applications, materials to be moved, ends and delivery.

Specifications of the hoses and couplings are based on critical simulation tests of actual site conditions conducted at our Lalru and Faridabad manufacturing facilities in Punjab and Haryana.

They include impulse tests, ozone tests, volumetric tests, and for oil swell and permeability test, based on which, the additional tough cover is suggested on the hoses.”

Normet products are aimed for safety, productivity and cost optimisation for all customers in UG Construction mainly tunnelling and mining. “We have been carrying large scale advancements in our all our range of equipments accordingly.

This is exhibited in our new Utimec LF 100 dumper. Though the typical application of the dumper for muck and blasted materials evacuation is for underground mining due to its high dump bucket capacity @ 12.5 cum, the equipment can find its application for UG mining, as well as for small diameter tunnelling jobs as it features turning radius,” informs Mr. Mukhopadhyay.

He adds, “Installation of hoses through routing in the TBMs and other tunnelling equipment is done by our application engineers in consultation with the OEMs and the end users. The application engineers, while installing the hoses also take into consideration the exact requirements for ease of replacement, when necessary.

Currently, we have six application engineers, and we will be further strengthening the service and support arm of our company.”

Evacuation

“Given the upcoming opportunities in tunnel construction, we are broadening our marketing strategy to make a foray into tunnel construction, apart from our core business of underground mining,” reveals Mr. Rajeshwar Singh, Managing Director, GHH India Mining and Tunnelling Equipment (Pvt) Ltd. He adds, “We are well positioned with our wide offerings of compact design loaders of 3-5-6-10-11-14-20-21 tons for use in tunnel construction of 2.5 – 5-meter radius, and articulated dump trucks of 16 to 63 ton payload capacities. The products, are more suitable for underground mining as they are more cost effective.

However, with their higher levels of productivity, the loaders and dumpers are also suitable for bigger tunnel infrastructure tunnelling projects for rapid muck evacuation. We will be promoting the products in the tunnel construction sector as a concept, given their advantage in cutting down deployment of large number of machines for muck evacuation. Further, our strategy is to position the loaders and articulated dumpers as a packaged offering by indexing the loading and hauling requirements through carrying out precise calculations.”

To promote its higher capacity products, GHH Fahrzeuge India is eyeing road tunnel projects with larger construction components that include main and escape tunnels, which will make them more suitable in meeting project requirements with higher muck throughput. It is also promoting its HRE tunnel excavatorfor hydropower tunnelling jobs as the single equipment can undertake drilling, bolting, shotcreting and loading.GHH, which

Normet’s business line comprises of underground tunnelling equipments, construction chemicals and rock bolts.

The Way Ahead

ARTICLESTORY COVER There is great scope for tunnelling in many parts of the country, especially in developing urban infrastructure, underground rail and road networks, and transportation in mountainous regions.

More refined designing capabilities, analysing instrumentation data, detailed geological exploration, more mechanisation and customisation of equipment as per projects’ requirements, will enhance the construction industry’s ability to foresee uncertainties and thereby pre-empt potential risks, reduce construction time, meet project completion deadlines and generate revenue.

Construction Technology for Underground Metro Tunnel Boring Machine (TBM) During the past decade, tunneling construction has gained a swift momentum in India. The metro railway projects throughout the country showcase varied technological requirements as far as tunneling in concerned.

Tunnel Boring Machine (TBM) Tunnel boring machines, also known as TBM, are used as an alternative to drilling and blasting (D&B) methods in rock and conventional “hand mining” in soil. Tunnel boring machines have the advantages of limiting the disturbance to the surrounding ground and therefore they are able to produce a smooth tunnel wall. This also helps in reducing the cost of lining the tunnel, and therefore this method of tunneling is suitable to use in heavily urbanized areas. Tunneling with tunnel boring machines is much more efficient in comparison with drilling and blasting and results in shortened completion times when they operate successfully.

On the other hand, drilling and blasting method remains the preferred method when the civil engineers have to work through heavily fractured and sheared rock layers.

ARTICLE EXCLUSIVE INTERVIEW

Kshitish Nadgauda, Senior VP & MD – Asia, Louis Berger, shares information on the challenges encountered during tunnelling in the mountainous terrains of J&K and in the busy streets of Mumbai.

Exclusive Interview of boost tourism and economic growth in the region. The highway

L

ouis Berger has completed many challenging tunnel projects across the world; please share your experience in one of India’s strategically important tunnel projects.

In 2004, the National Highway Authority of India (NHAI) selected Louis Berger in a joint venture with LRP Consultants to prepare the feasibility study, detailed project report (DPR) and engineering designs for the four-laning of the Udhampur to Banihal section of National Highway 1A, now part of National Highway 44. The project would eventually include replacing the existing 41-km (25.5-mile) long mountain road stretch with the 9-km long (5.6mile) Chenani-Nashri tunnel, which would become India’s longest roadway tunnel.

The design and construction of the Chenani-Nashri tunnel was a challenge not only due to inclement weather conditions but also due to the sheer size and magnitude of the project, and the prevailing soil and rock conditions in the area. Additionally, preservation of the endangered chinar (maple) tree forest was a mandatory requirement.

Srinagar was connected to Jammu and the rest of India by the old National Highway 1A, a narrow two-lane highway passing through treacherous terrain and some of the steepest landscapes in the world. Widening and realignment of the highway, including with new all-weather tunnels through steep rock beds, was needed to improve safety, decrease travel time and minimize roadway closures during adverse weather conditions.

The 9km-long tunnel reduces the travel distance between Jammu and Srinagar, the state’s two largest cities, by 30 km (18.6 miles), cuts travel time by about two hours, and is anticipated to

28

realignment will also help preserve forests in the ecologically sensitive Patni Top area of the state.

Louis Berger overcame all the challenges by working closely and collaboratively with our client, the NHAI, the consultant, contractor and other stakeholders, and ensured successful delivery of the project, minimizing or avoiding delays, and within the original budget. Today, the Chenani-Nashri tunnel is widely acclaimed as India’s longest and safest roadway tunnel in the heart of the Himalayas.

What steps were taken to overcome the challenges while building the Chenani-Nashri tunnel?

The old National Highway 1A was a narrow two-lane highway passing through challenging and rugged terrain, with steep gradients. Widening and realignment of the highway, including new all-weather tunnels through steep rock beds, were needed to improve safety, decrease travel time and minimize closings during adverse weather conditions.

The two major challenges were the terrain and the type of rock in the mountains all the way from Udhampur to Banihal. Our team assessed the environmental and social impact of the project, including cultural properties, natural habitats and involuntary resettlement. In fact, during the design phase, since the team had to go through every parcel of land with precision, the expert teams had to walk multiple times along the 122km length over a period of 4 days to verify the compatibility of the design with the site conditions! The team overcame these challenges by designing the alignment with great precision, with several iterations to ensure accuracy. We also had to ensure during the design phase that the hill cutting was optimized, and minimize the overall ecological impact, without disturbing the forests of rare Chinar (maple) trees.

Louis Berger Tunnelling Through Challenges

METRO RAIL NEWS | APRIL 2020 | WWW.METRORAILNEWS.IN

ARTICLE EXCLUSIVE INTERVIEW Another challenge was the large number of monkeys along the stretch. So, we incorporated in the DPR monkey-crossing structures at required locations - this is unique to the Chenani Nashri project!

The design of bridges and viaducts was also challenging due to the necessity of tall piers on account of the mountainous terrain and the high-risk seismic zone. Due to the nature of the rock, it was essential to stabilize cut slopes to avoid landslides. Our geotechnical experts studied the type and nature of the rock along the 122km alignment to design unique slope stabilization measures. Wherever feasible, tunnel options were explored, and accordingly, small tunnels at 8 locations were designed.

W h at a re t h e i m p o r t a nt co n s i d e rat i o n s d u r i n g t h e development phase of tunnel projects?

Foremost amongst the challenges encountered is the selection of the site and optimum (shortest) alignment with horizontal and vertical geometry befitting the importance and category of the project, and other design criteria. Establishing the location of tunnel portals can also be a challenging task. The design must also allow for smooth connectivity of approaches to the tunnel.

Perhaps the most challenging task is the assessment of site geology, collection of geological maps, and establishing and executing an adequate geotechnical investigation program to inform the design of the tunnel and to ensure that the design is optimum. Ground movement, ground deformation and building settlements have to be minimized. It is, therefore, also important to assess and establish the construction methodology and fronts for construction such that safety is ensured at all times, along with minimum cost and duration.

Today, India is probably the fastest growing market for tunnel construction. International construction techniques such as New Austrian Tunnelling method are being implemented, TBMs are being used, and international norms and fire safety codes along with evacuation preparedness are being followed.

For engineers, tunnelling in hilly areas means dealing with difficult terrain conditions, in-situ stresses, ingress of water and gases, geothermal gradient, high-level of seismicity, etc.

What technical know-how does Louis Berger provide for such projects?

For the DPR of the Chenani-Nashri tunnel project, Louis Berger conducted the design of all proposed tunnels in accordance with the New Austrian Tunneling Method (NATM). The design included civil works, electro-mechanical works (ventilation) and lighting, as well as state-of-the-art Control Centres. Geological investigation plays a vital role during the design and construction stages to decide a suitable construction method and support arrangement. The advanced investigation tests are been carried out according to terrain conditions such as electromagnetic geophysical surveys, hydraulic fracture test, flat jack test, stress relief techniques, strain recovery methods, borehole breakout method along with fault slip data analysis for measurement of residual stresses etc. A laboratory is set up at site for routine investigations to compare the design assumptions and construction approach. Further fore-poling is carried out and cores are collected before excavation cycle to ensure expected geological scenarios and avoid unforeseen surprises.

How do you rate India in terms of its technology and expertise in tunnel construction?

Today, India is probably the fastest growing market for tunnel construction due to the large number of roadways, rail and metro rail projects that are being implemented on a phenomenal scale as never before. In addition, large water supply, sewerage and storm water drainage tunnels are also being constructed. As a result, there is a large number of international consultants and

contractors specialized in tunnels, present in India.

International construction techniques such as NATM (New Austrian Tunnelling method) are being implemented. TBMs (tunnel boring machines) that are manufactured and imported across the globe are also being used. International norms and NFPA codes (National Fire Protection Association) for safety and evacuation during fire are being followed.

What are the current tunnel projects being undertaken by Louis Berger? Please elaborate on one of them. Besides the Chenani-Nashri tunnel, Louis Berger recently conducted the design review of a 46km long railway tunnel between Karad and Chiplun. We are also working in the capacity of PMC on the Mumbai-Pune Expressway. The augmentation project includes 10km long twin 4-lane tunnels along a new alignment of the expressway in the ghat section. In addition, we are part of the General Consultant consortium for the 33-km long Mumbai Metro Line 3 that is presently under construction. Apart from these projects in India, we have extensive tunnel design and construction experience on projects worldwide. All tunnel projects have their unique and distinctive features and challenges. The tunnelling work for the 33km-long fully underground Mumbai Metro Line 3 project is no exception. This line extends from Cuffe Parade in South Mumbai to the Aarey Milk Colony in the western suburbs to the north. The underground alignment passes under a diverse set of developments including high-rise buildings, heritage structures, delegate buildings, residential and commercial developments including hutments and the Mithi River. The project includes 26 underground stations and one at-grade station. The assessment of the geology and geotechnical profile of the underlying strata along the alignment was a significant challenge, since Mumbai comprises seven islands. The varying strata includes hard rock, shale, as well as backfilled soil. The tunnel boring machines were therefore designed to suit the ground conditions.

The survey of existing buildings that was conducted was also crucial to categorize the condition of buildings as good, moderate or severe. This was important to ensure the stability and integrity of structures during tunnel construction. Protection of heritage buildings is also of utmost importance. Instrumentation to measure ground deformation and vibrations was placed in this regard. In addition, mapping of existing utilities and then relocating them if impacted by the alignment also needs to be done carefully.

eating, Ventilating and Air Conditioning (HVAC) is a type of technology system for indoor and environmental vehicular comfort and it is very useful in providing the thermal comfort and an enhanced air conditioner technology used in industrial complexes, underground metro stations, and other blocks.

It was specially designed to control the temperature environment where it works. It controls an underground temperature via cooling and heating. Besides, through monitoring the distribution and movement of air in a type of underground area, it controls the humidity level of the atmosphere.

The Heating, Ventilating and Air Conditioning typically deployed in large industrial skyscrapers, buildings, Metro coaches and large interior environments.

The process of exchanging air in any particular area to maintain the air quality which includes temperature control, moisture removal, Smoke, dust, heat and prevent the stagnation of the interior air is known as ventilation.

For Urban Public transport, the Metro Rails are main a consumer of almost 30% of the energy utilized to replace the heating ventilation and Air Conditions as the backbone. The HVAC system also contains many types of subsystems like Water-side subsystem and the gas side sub-system.

For shedding light on serving of cooling systems at metro stations Sales Manager of CAREL Group summaries that for metro systems solutions can be utilized that lower the ambient temperature with the use of water as the cooling source.

In the encircling air when 1 kg of water evaporates it occupies approximately 700 W of energy. If the evaporation method is triggered via a device with weaker power consumption, such a device would be greener than comparable traditional cooling equipment like a chiller. Having significantly lower energy loss, evaporative cooling systems are consequently cost-effective in the time of summer.

HVAC has also used in the many metro stations such as Delhi Metro, Mumbai Metro and other metro project in the country for removing fumes, heat and vapour from heat radiated by the Water coolers, Escalator and the light fitting etc working at all the underground metro stations.

Extracting heat from the Air-conditions and other equipment’s that is working in the underground metro stations as this cannot be extracted by simple ventilation mainly the humidity and outside temperature of air is high.

In the stations in terms of commuters comfort conditions are appropriately considered within the premises of stations.

Mauritius Metro Express Relies On The Latest Overhead Line Technology With TENSOREX C +

W

ith the opening of the first 13-kilometer section of the new Mauritius Metro Express light rail line, a new chapter in local public transport begins on the island in the Indian Ocean after the last passenger train service in Mauritius was stopped in 1964. In 2017, construction began on the new 26kilometer route, which leads from the capital Port Louis through its densely populated metropolitan area and connects it to the four important cities of Quatre Bornes, Rose Hill, Vacoas and Curepipe.

The first section of the north-south route serves nine stops to Rose Hill, the second will be completed in 2021 and will include 10 further stations to Curepipe. Then the operators expect around 55,000 passengers a day.

Long service life and resistance to salt water required The Indian construction company Larsen & Toubro received the order for the turnkey construction of the route. The planners became aware of the innovative TENSOREX C + spring tensioning system through PFISTERER projects in Mumbai, India, and quickly recognized the benefits. "We were looking for the best possible technical solution for the new light rail line," reports Stuart Woodsell, Head of Sales, Rail at PFISTERER. "The climate in Mauritius offers a number of technical challenges that can be easily overcome by using TENSOREX C +. That is why Larsen & Toubro approached us early to discuss the possible deployment. " Due to the proximity to the coast and a relative air humidity of around 80%, a high level of salt water resistance and absolute rust resistance are mandatory for the steel parts of the spring tensioning system in Mauritius. "This requirement is also in demand in other regions worldwide and we can meet it with our products," says Rob Renshaw, Commercial Sales Manager Rail at PFISTERER. "The advantages of TENSOREX C + are particularly Evident in long-term operation. Our maintenance-free retensioning system is a Fit & Forget product with a lifespan of 3040 years, even in rough sea air. �In addition, the PFISTERER team supported the technical planning and also supplied design-

specific connectors, clamps and small steel parts for end closings that were tailored to customer requirements.

Maintenance-free, space-saving, easily installed TENSOREX C +, as a tensioning system for overhead lines on electric railways, ensures that tensioned ropes and contact wires always remain at the defined altitude, even when the length c h a n g e s d u e t o t e m p e r a t u re c h a n g e s . T h i s re l i a b l e compensation is a basic requirement for smooth train operations.

Instead of heavy and space-consuming concrete or cast steel masses, the TENSOREX C + uses a compact spiral spring and an eccentric disc to provide the permanently required tension weights and cable guides on the mast are completely eliminated.

TENSOREX C + works without lubricants and is therefore completely maintenance-free over its entire service life. The patented system is delivered ready for installation and can be assembled within a very short time. Thanks to its small size, it is also suitable for easy installation in tunnels. In the event of a rope break, the system is also completely reusable. The new rope is simply attached - done.

Rapid expansion of the route planned In the ongoing project in Mauritius, PFISTERER has delivered 115 units of the tensioning system for the first two sections of the Mauritius Metro Express, including the associated mast mounting brackets and the rope safety kit. PFISTERER received the order in February 2019, the first delivery took place in June and the tram line was able to start trial operations on October 3. The second section of the route is scheduled to open in 2021 and plans are already underway for further expansion of the line up to the direct connection to Mauritius' national airport.

TECHNOLOGY UPDATES ARTICLE

Blockchain: The Wheels Of Future Railway Blockchain technology is one of the noteworthy discoveries in digitization where the coalesce of cryptography with data authentication on a distributed network was initially targeted to make online financial transactions secure but its unique advantages are now opening window to various other commercial applications such as - smart contracts, car industry, healthcare, internet of things (IoT), marriage certificates, e-voting wills and insurance, food safety and travel. Let us investigate this technology and its suitability to address the issues of Railways.

Blockchain technology can be perceived as a kind of open distributed digital ledger that can record transactions between two parties efficiently and in an authentic way.

Rather than relying on a third trusted party such as a bank, it uses a peer to peer approach where verification and validation are done by the nodes of the distributed network. Not only this technology eliminates the involvement of a Third Party for the purpose of authentication (very often these Third parties become the source of security breach) but also chops the extra transaction cost that goes to them. Using this approach, the possibility of fraudulent transaction is minimized to zero because the group of transactions called blocks is not only protected by digital signature that subsequently goes through a mathematical puzzle for time alignment, but also needs to be the longest and fastest one in the network amongst the existing good nodes to succeed.

This means that all transactions are fully secured and fraudulent transactions, if any shall form a long chain of such blocks which will be transparently visible to all parties clearly identifying the perpetrators for disciplinary action and also such fraudulent transactions will be next to impossible to get overlooked. Thus this mechanism is completely secured from hacking by outsiders through spoofing, phishing, etc.

Traditional System of Financial Transaction

Features useful for Railway Applications Beyond the endless financial applications that would disrupt the economy of countries, the possibility of Blockchain technology to circumvent transportation industry comes from its several unique characteristics: Cryptographically secure: Owing to the consensus mechanism, cryptographic security has a high threshold. Transparency: The entries made on a public Blockchain cannot be altered and hence offers a time-stamped version of the „truth?.

Integrity: The data on Blockchain is always complete, accurate, reliable and authentic. Once consensus is achieved on a data entry by the miners, it cannot be altered. Moreover, the data available in a single public ledger shared among several parties is more reliable than multiple databases.

Cheap and Efficient: Blockchain eliminates the need of a centralized repository and authentication by a third dedicated party which reduces the cost and at the same time offers more efficiency.

Possible Applications in Railway Industry In Blockchain, all participants share the same copies of relevant data. In concrete terms, this means that all trains can communicate with each other via smart contracts and with the track elements such as signals, points, track circuits or level crossings. This simplifies the infrastructure and the availability of the entire system can also be improved. Initial tests in Darmstadt’s dispatcher training facility for infrastructure operators in Germany show that the trainsets can choose their own routes, lock them and release them again. This shall happen without a central control centre and yet without a conflict. The state of the infrastructure elements is recorded in a tamper-proof, transparent general ledger and is constantly updated. Conceptually, Blockchain can be used for all other transactions for example, for checking the driver’s license and driver authorization and billing the infrastructure. As of now, the technology is in an experimental state where potential use cases are being developed and tested to affect the following areas: Reward Points/loyalty schemes Rewarding travelers for their continued purchasing of a travel ticket has become an important marketing tool for credit card companies and railways. For this, loyalty programs need to be accurate and user-friendly to ease the complexity involved in keeping an account of passenger’s loyalty points and redemption as per the defined policies. Recently, San Francisco has developed a Blockchain-based loyalty Software named ‘Loyyal’. The platform not only seeks to improve the interoperability between multiple schemes but also allows invoicing and payment transfer between partners using smart contracts.

Redemption of reward points from one service to another such as automatic credit of points after a train journey, which can further be used to pay an online cab service shall add to a better travel experience.

Improving identity management in travel For undertaking the journey in any reserved class on Indian railway, a prescribed proof of identity shall be available online. On the blockchain, identification of the passenger, change of booking or enquiry can be done using traveller IDs which eliminates the need to carry any hard copy of id proof during travel. Predictive maintenance: Trains have complex mechanical and electrical systems with hundreds of thousands of moving parts. To deliver a reliable service, trains need regular maintenance that can be triggered when a certain mileage is reached, after a particular time period, or by monitoring the condition of parts.

Condition monitoring involves checking the operation of the equipment and only changing something if it shows signs of deterioration.

Will suburban rail move ahead?

T

he government’s economic survey of the Indian economy for 2019-20 introduced a new worThalinomics” to talk about how economics relates to the common man’s daily encounters with food. But what about the government’s approach to the common man’s encounters with his daily commute on heavily congested roads in densely populated cities like Bengaluru?

What does the Government intend to do about the suburban rail project that has failed to “kick-off” despite repeated mentions in budget speeches year after year? The finance minister quoted statistics meant to better the lives of Bengaluru’s harried citizens, Toiling through badly dug up roads, rapidly increasing vehicular population and delays in implementing the metro rail, in a city recently adjudged to be the most congested city in the world by a Netherlands-based global provider, setting aside 18,600 crore in the 2020-21 Union Budget, towards a muchdelayed suburban railway project, a mass transit solution to decongest Bengaluru. The Centre will provide 20% equity for the project and facilitate 60% of external Funding.

Most Bengalureans are aware of the project’s details -- a 148km network with 56 stations for the suburban rail system with four corridors: KengeriWhitefield, KSR Bengaluru C i t yRa j a n u k u nte, N e l a m a n g a l a Baiyappanahalli and Heelalige-Devenahalli, with the Karnataka Rail Infrastructure Development Company (K-RIDE) tasked with ensuring project progress.

The cost of the suburban rail project is known to every rail commuter of Bengaluru, but what about actual Allotment? Of the Rs 18,600 crore grandiosely set aside by the Finance Minister Nirmala Sitharaman, the South Western Railways has detailed a mere Rs 1 crore as a token amount for the financial year 2020-21. In its Pink Book, a document that outlines this budgetary allocation, this amount may be used for the construction of elevated and at-grade corridors to augment existing line capacities but not for laying lines or construction of the 56 stations across the city. Bengaluru’s harried citizens are unlikely to benefit from the knowledge of the amount set aside, for this is the third time a similar announcement is being made in the Union Budget with the project continuing To remain at the start line.

Having elected the same ruling party at the Centre, the state (and the BBMP), Bengaluru’s harried citizens next awaited the Karnataka government’s budget, presented on March 5, to find the state government had earmarked a grant of Rs 500 crore during 2020-21 and proposed to execute the project through the Rail infrastructure Development Company (Karnataka) Ltd (KRIDE) through a special purpose vehicle (SPV) to be formed to implement the project.

The repeated mentions in the budget by the government is only causing confusion about the project, pointing towards the lack of a coherent agenda. The ‘please all’ announcements, without corresponding allocations, have made citizens sceptical about the government’s seriousness, demonstrating a lack of significance for budget citations. The question for Bengaluru’s commuter now is: What could make the government roll out the project? Electing the same party at the Centre and the state does not seem to be enough, nor Are the people’s representatives being able to convey the commuter’s agony to the party’s top brass. Given the intensity of India’s slowdown–successive quarters of slowing growth, and of agovernment living beyond its means -there is one way, however, that would make the Government roll out the project: bringing in a private sector partner.

With modern revenue collection systems, working on RFID (radio frequency identification) technology, ticketing systems today prevent leaks and pilferage, and are relatively foolproof.

With revenues guaranteed in a growing city, several private sector players would want to participate in Bengaluru’s suburban rail project, preferably through a special purpose vehicle, independent of the Indian Railways, able to determine the fare, routes and manage operations.

Although the Suburban Railway Policy stipulates that a state government needs to be the primary shareholder of any suburban railway p ro j e c t a l o n g w i t h t h e central government but without any private player, presumably because suburban rail projects need to share existing Indian Railways’ tracks and logistics, this could be tweaked to bring in funding through a Public Private Partnership (PPP), with the government continuing to hold a minority equity stake. Privatization in the Hyderabad metro rail project, where the SPV has a private sector partner, Larsen & Toubro, has been a success story. At worst, some of the 56 stations could be privatized through MoUs similar to the one signed between Namma Metro and Infosys Foundation for development of the Konappana Agrahara station in Electronics City.

Dependant on private sector pools of capital, the government will be forced to listen to a private partner who cares about growth and investment. The finance minister’s clearance of longpending cabinet notes and the Cabinet Committee for Economic Affairs’ okays would then become formalities aiding the state government and K-RIDE officials to allocate land and funds.

The government’s economic survey of the Indian economy for next year could then introduce a New word “Commuternomics”!

Automatic Train Supervision

A

TS is automatic train supervision which control, monitor and track the train through GUI based application, approach to get better performance . The end user controls signal train to field and field to train for better effectiveness. ATS communicates with interlocking IXL and Vehicle on-board Controller (VOBC=ATP+ATO=ATC) for simultaneous convergence of signal. ATS works as server -client model where all operation done by server as Scada and all control commands are given by client as end user workstation. All information goes from client to server vice versa to execute the commands with the regional authority.

All server connects with devices like ZC, IXL, VOBC through switch and router as per AT S / D C S d e s i g n a r c h i t e c t u r e a n d authenticated by license or other security pattern.

There are three basic type of ATS in rail technology which is divided as per region control.

1-Central ATS: -Central ATS controls all guide-way interlocking with authority control and Central ATS installs in OCC (Operation control center).

2-Local ATS: -Local ATS workstations be installed at every station. Local ATS will have all control and information of guideway based upon its own zone or section where ATS has presentation of field state in this region and, given appropriate authorization, control of the region.

Workstations at non-interlocking stations will display information for the local station.

3-Emergency PC or VDU: End user us VDU

(Visual Display Unit) when Central and local ATS having technical issue and then they o p e r a t e E C P C / V D U w h i c h d i re c t l y connected with IXL controller without any ATS interface. It is same as ATS application which has limited access to operate train and connected directly to IXL. ATS Server and Client Model:

ATS Server: The Central, Local, and Depot ATS are deployed as Active/Passive server pairs. Only one server is Active at any time.

The Active server executes the ATS algorithms, processes user commands and issues commands to the interlocking equipment. The Passive servers accept state changes (replication) from the Active server and cache this state for use if activated in the future. Passive servers also maintain communications with interlocking equipment (at a reduced polling frequency) and provide this communication status to the central Operator. Passive servers do not execute ATS algorithms or send commands to the field and can only accept one Operator command: Activate. All operating Passive or Active servers advertise their current state to all others. The Backup ATS is non-

ATS Client: The ATS Operator interacts with t h e Tr a i n C o n t r o l s y s t e m v i a t h e workstations. The interface is menu and mouse driven. All workstations are configured in such a manner that on power up, they automatically load the ATS workstation application software and display the guide-way. All ATS workstations are functional regardless of which ATS server is Active. All ATS Operator input actions are logged to the archive server database.

Functional ATS Architecture Managing Train Operation from ATS: Train Operation from guide-way is to manage routes and its direction of train from where operator controls the train along with field signaling gears. All signaling gears on field are controlled by IXL and commanded by ATS GUI application and it is like SCADA application. Different system provider has different platform for executing the application. Trains send information of redundant VOBC, speed, traveled distance, emergency break, automation mode etc. to ATS Traffic Management: Traffic Management is term to control the train on guide-way.

Every train has its unique ID with rollingstock code, distance code and trip code so that end user can check trip performance for individual train run. Junction Box and Crossover management is one of function For traffic management to provide better performance.

In traffic management systems, regulation decisions are based on monitoring traffic information. Monitoring data are generally used to update a traffic model in case of disturbances. The traffic model helps to evaluate both the impact of disturbances and the impact of regulation decisions. compiles the state-of-the-art in infrastructure and operation modelling.

Traffic management optimize traffic during any kind of disturbance or delay, It always evaluate the buffer time and run assignment to cover up the overall performance. traff ic management depends upon dwell, headway, train

capacity, operation restrictions, guideway constraints, crowd on platform and timetable variables.

The traffic model is designed for traffic supervision and has been integrated into the ATS module of a modelling of a railway system where all traffic scheduling is defined as track to soft node with train arriving and departing data.

Headway Management : The headway calculation for any railway system mainly relies on the preconditions given by track (distances, grades, speed limits, layout), train (speed, forces, braking, lengths), signaling design (signal positions, routes), ATP design and time table (arrival and departure times, trip planning, dwell times).

Time-Table management: Timetable Management is part of ATS where user makes a timetable for train as per operator’s requirement. There are many parameters to assign time table to server like Travel Time, Buffer time, Dwell Time, Headway etc .

It has all information related journey (Trip) from one terminal station to another terminal station with train capacity and its defined headway. Before launching the timetable, operator need to resolve all conflicts related trips dwell and circulation of movement in off-line timetable.

Automatic Train Regulation: Function automatic train regulation will be used in Automatic Mode but the individual dwell time will be entered by the operator so that the dwell time is not adjusted by ATR automatically and always a fixed value of dwell time (Based upon project requirement) is sent to the train.

Automatic Train Regulation manages the dwell time and train run type for trains with a run assignment. It also calculates the schedule and headway adherence of each train for presentation to the ATS Operator.

A u t o m a t i c Tr a i n Re g u l a t i o n (AT R ) determines the dwell time and the speed profile for a train on an assignment. ATR uses two types of regulation - Schedule

METRO RAIL NEWS | APRIL 2020 | WWW.METRORAILNEWS.IN

Regulation and Headway Regulation. ATR in Schedule Regulation adjusts the dwell and the speed to make the train arrive and depart at the time specified in the schedule.

ATR in Headway Regulation adjusts the dwell to make the train separate from the previous train by the same headway as specified in the command Maximal dwell time : The maximal dwell time is a predefined time a train stop cannot exceed. It is used by regulation to reduce the advance of regulated trains. It is defined during data preparation phase and based on signalling application studies.

Minimum dwell time : The minimum dwell time is a predefined value indicating the minimum time a train can stop on a platform loading passengers.

It is used by regulation to reduce the delay of regulated trains. It is defined during data preparation phase and based on signalling application studies. It can be modified by the operator.

Nominal dwell time : The nominal dwell time is the time a train stops on a platform when it is not regulated or else if it is on time. It is a predefined value.

It is defined during data preparation phase and based on signalling application studies.

Performance Management: Performance Management where we check performance of train, based upon delay between scheduled and real based train movement scenario.

ARTICLE The destination matters, but increasingly, the journey does, too. Today’s metro train operators have a challenge that didn’t exist in the golden age of the steam engine: keeping all those passengers and their devices online.

Time Distance Graph (TDG) is an ATS Software component, intended to help users to monitor and regulate the train traffic circulation. In the account of TDG connects with (e.g. Timetable Management, Estimated Time of Arrival, Infrastructure Management, etc.), performance tool gives a clear graphical view of the train circulation, infrastructure state, abnormalities and detected conflicts.

Performance tool generates the delay and performance report for better understanding over operational planning.

Time Distance Graph: TDG can be used either in online mode or in off-line mode, in order to plan in advance, the train circulation taking account the situation of the infrastructure or temporary modifications to timetables. It is easy to use and highly configurable. It allows the operator to see in advance problems on train circulation in a clear and intuitive way, then to act quickly to solve the problems. TDG displays:

Ÿ I n f r a s t r u c t u r e p r o v i s i o n s (s p e e d restriction or way restriction) by covering the area involved in the infrastructure provision. Ÿ Abnormalities (general problems that can create any disturbance on the traffic circulation). Ÿ Conflicts between trains or between a train and the infrastructure by means of an appropriate symbol. TDG is a convenient summary tool to manage the traffic in a smooth and efficient way.

Delay Report: Delay report comes with calculation of scheduled and real-time train operation with the analysis of TDG graph and timetable scenario. Delay report helps to get the delay impact on trip.

ATS External-Internal Interface: For ATS interface, ATS server connects with telecommunication system or other stack holder (PSD, SMS, AMS) through IEEE 802.3/802.11 protocol with interface firewall and gateway router and it exchange the information bits to telecommunication system and gets acknowledge with

Synchronization of secured application layer (HTTP, SOAP, WSDL etc).

Data Communication Network (Fibre Optic Tr a n s m i s s i o n S y s t e m ) p r o v i d e s communication channels for the transmission of the voice, data and video signals. Data and control flows between the central ATS, local ATS and depot ATS follow channel communications of the Telecommunication Network with the help of interface filter.

The ATC and ATS sub-systems of the signalling System manage the interfaces with the Data Communication System.

Connectivity on track with Trulifi Across the globe, metro train travel is having something of a moment. Metro is not onl about connectivity – it’s about convenience, too. For time-constrained travelers, it’s easy to see the appeal of riding the metro trains: avoiding the road traffic downtime, arriving directly at your destination instead of having to drive for an hour or looking for parking, and clawing Back your travel time that can be used More productively, whether that’s catching up on your emails, or relaxing with a Netflix binge.

Light years ahead As the leader in lighting innovation, Signify is addressing the challenge of connectivity on board, and amazingly, we’re doing it all through the power of lighting. Not only can lighting now provide connectivity on the go, but it does so at blistering speeds that far surpass the WiFi connections we’re all used to. And this flawless connectivity is of course in addition to great quality lighting.

Signify’s latest offering called Trulifi is a connectivity technology that uses light waves to enable an internet connection that’s fast, stable and reliable. It’s great for super speed internet in the workplace, and for transportation services like metro rail, the benefits are further multiplied. What’s more, unlike the radio spectrum, the light spectrum is license-free. This means no upfront investment for network operations in government-issued spectrum Licenses.

No compromise Indeed, internet connectivity is one distinct advantage that the metro has over other forms of transport, and it’s a topic on which travelers are unwilling to compromise.

Going forward, passengers expect to stream high definition movies, upload heavy files, and make video calls, every kilometer of their journey. And in our connected world, the train itself has connectivity requirements; for example, high definition cameras collect security footage that must be offloaded on physical hard disks for processing.

When you look behind the curtain, how to keep the connection going is a substantial Question that operators must face. At home, our WiFi router passes a radio signal to our TV or smartphone in more or less a straight line. A large, moving vehicle however presents more challenges. Trains

ARTICLE are full of metal surfaces and also full of people. Both of these elements affect the ability of radio transmissions to reliably hit their destinations. Heavy, constantlymoving carriage couplings that lie open to the elements do not play well with the data cabling needed to link carriages to one another. And linking the train to the outside network requires costly cellular data connections, which are also unable to penetrate tunnels or mountains along the way.

Stellar speeds By adding Trulifi to the connectivity mix, seamless connections and stellar speeds become possible. High definition streaming and even online gaming are on the table.

Right now, Signify is already working with Latécoère to provide Trulifi on commercial aircraft, connecting seat-back screens to fast Internet with a speed up to 250 Mbps.

Trains and buses are a logical extension.

Connectivity could also be extended to passengers’ own devices through a seat point USB connection in the future. As we witnessed with the adoption of WiFi; when the infrastructure becomes more widespread, we’ll likely see LiFi receivers built into a new generation of laptops, tablets and eventually, smartphones, rendering a wired connection unnecessary.

In future, LiFi can revolutionize the way we make the connection towards the train. LiFiequipped poles, paced at intervals along the track, follow the moving vehicle, beaming high speed internet underground, through tunnels and even hilly terrain.

Trains that talk Behind the scenes, Trulifi offers a robust wireless platform to connect the growing demands of digital equipment and IoT sensors between train wagons. It offers the connected train greater reliability and safety and also provides “plug and play” wireless communication when regrouping trains or doing maintainance. Those chunky security video files that are currently stored on local hard disks in the train along with other data can be downloaded and processed at high speeds the moment the train pulls into a station, improving passenger safety.

Arthur C Clarke famously said that sufficiently advanced technology is indistinguishable from Magic. You could also say that really effective technology is completely invisible. For passengers, uninterrupted high-speed internet connection is something that’s supposed to just work. Meeting that expectation is a differentiator that can help keep metro train travel on its upward trajectory – and help people and the planet too.

hands or using an alcohol-based rub frequently and not touching your face.

The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it's essential that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).

At this time, there are no specific vaccines or treatments for COVID-19. However, many ongoing clinical trials are evaluating potential therapies.

WHO will continue to provide updated information as soon as clinical findings become available. So, it is essential to maintain social distancing.

GOI Order no. 40-3/2020-D-on dated 24.3.2020 on the measures taken by Ministries / Department of GOI, State/Union Territory Govt and State / Union Territory Authorities for containment of COVID-19 epidemic in the Country that the offices of GOI, Public Corporation will remain shut.

This disease is impacting in various sector such as global economy, environment, railways and metro rail sectors including France, Spain, Italy, The United States, India.

According to a joint report of the World Health Organization of 2019 and the World Bank estimates the consequence of such a pandemic at 2.2%-4.8% of global GDP. That was very well before the world acknowledged the infected disease COVID19. All the Metro Services are not Shut till the lockdown. During this lockdown period, all the metro corporations are sanitizing their premises to reduce the chances of further infections or spread of COVID-19.

The world's most extensive lockdown hitting out on all the sectors such as shops, factories, markets, and all the visiting places are closed, along with this the public transport suspended and development work stopped, as PM urged people to stay at home and maintain social distancing.

The Metro and Rail operations that have now stop till 14th of April 2020, which were

Along with that, the DMRC, KMRCL, HMRL and other metro corporations are taking actions to resist the deadly coronavirus which is affecting many people on the world wide.

When the metro services are closed due to COVID-19 in terms of the disease internal operational maintenance works remain functional and safety of the system is being looked out of by the CISF. Meanwhile, the Indian Railways also made a significant contribution it would modify 20,000 of passenger train coaches into quarantine centres to support around 3.2 lakh novel coronavirus patients in and out of the country to augment the quarantine facilities being created in the Country.

Impact of Coronavirus Western Railway suffers Rs 178 crore loss due to lockdown Train cancellations on account of the lockdown for the novel coronavirus outbreak have led to losses of close to Rs 180 crore, Western Railway said on Monday.

The loss was Rs 78.50 crore before March 22 and Rs 100.03 crore between March 23 and 29, it said in a release. WR has suffered the loss of Rs 178.5 crore in suburban and

Non-suburban train operations till March 29. In Mumbai division, over 9 lakh passengers cancelled train tickets until March 29 and WR has refunded Rs 62.11 crore," it said.

Passenger train operations across the country have stopped from March 23 to enforce the lockdown for the virus outbreak.

I n d i a n R a i l ways a p p r e h e n d "enormous" rush to hospitals The Indian Railways comprehend an "enormous" rush to hospitals soon and have decided to hire the services of retired para-medical staff.

In a note to all General Managers of Zonal Railways and Production Units, the Railway Board on Saturday said: "keeping in view the pandemic situation because of the outbreak of Coronavirus disease, it is apprehended that extra para-medical staff will be required for handling the enormous rush expected in few weeks.

The Railway Board authorities the General Managers/Chief Administrative Officers/Divisional Railway Managers to engage retired Para-Medical Staff up to the age of 65 years or to hire para-medical staff on Contract basis for one month over and above the sanctioned strength depending upon the requirement. This would be a temporary measure.

ARTICLE An MoU signed between Urban Development Minister Madan Kaushik for Uttrakhand Metro Rail Corporation and S.D. Sharma, Director (Business Development) of Delhi Metro Rail Corporation in Dec 2019.

The DMRC was entrusted with the task of making a detailed project report (DPR) for the construction of ropeway in Dehradun.

DPR will be ready within the next four to six months. After this, the transport system will be started through ropeway in about two years.

ROPEWAY AND PRT AS MRTS

S

ince the Metro Rail projects are being rejected from Uttarakhand and many other states, especially in hills area and mountainous regions, now many state governments are looking forward to establishing the PRT, Cable cars and Ropeway systems as the public transport to increase the reach in their state.

The government is taking an interest in the passenger’s ropeway systems. It is also taken into consideration that the Ropeway system can be an alternative for offering urban transport.

Ropeways system is a sort of naval lifting device mainly used to transport light stores and facilities over rivers or ravines

Personal rapid transit (PRT) which is referred to as pod cars. This is a public transport mode emphasising small automated transports working on a network of specially built guideways. Personal rapid transit is a kind of automated guideway transit, a class

of system that also involves larger carriers to small subway systems. To implement this Ropeway system, the govt has asked to Delhi Metro Rail Corporation (DMRC) to execute this ahead. This step by the government to improve the transportation system seems to be very necessary as there is no option of Metro apart from Ropeways, Cable cars or PRT. This transit system has a lot of benefits also which are as follows - it is low pollution and crowding removal transit because this system has the lowest carbon emissions in the comparison of all the other transit options. Also, this transit system option is an old tested and tried option that is operating successfully across the world.

Ropeways system are very environmentally friendly till now because as we can see, there is no need to cut forests as they could not be under the corridor of the transit system.Apart from this, the government has also gone through the safety and grade of the services NITI Aayog has suggested globally accepted European CEN standards. Also, there are different standards available like Canadian/American standards but among that so many of the technologies to make s u re t h e s e c u r i t y of t h e ro p eways throughout market segments commencing urban transport, tourism, adventure, leisure, etc have taken by CEN standards as a standard for safest, highquality and the reliable ropeways systems.

In such a situation, the government has taken this critical step to better the public t r a n s p o r t s y s t e m i n t h e c i t y. T h e completion of this project will take two and a half years. This project will be completed at a much lower cost than the metro rail system. This project will cost around Rs 2,000 crore only.

Initially, two routes will be developed under the ropeway project.

There will be pods/cars with 10-12 passengers capacity run on the ropeway.

The first route will be developed up to Respna via Ghantaghar from FRI and the second route will be made from ISBT to Rajpur Road. It is considered a milestone for the purpose of improving the transport system of Dehradun.

The Uttarakhand government claims that till now the ropeway system is not being used for public transport in any other place and city of the country. In such a situation, Doon city will be the first city in the country to have a ropeway system as public transport.

After signing the MoU, the Uttarakhand government has also issued the first instalment of Rs 43 lakh to DMRC for making the DPR. It is pertinent to mention here that the Uttarakhand Government has spent over
