LAYOUT VISIT on 15 February at JOHN LEMON An interesting visit – especially for those who were first –timers. Much of the rolling stock is Lionel but one of the two oval tracks has an extra rail so that John can run S scale. The one photo is just of track to show this. It is estimated that there are >300 locos in his floor to ceiling cupboards and shelves. His train room is a treasure trove of railway stuff.

Thanks to Mike Smout for the images

LARGE PUBLIC LAYOUTS National show-museum “Grand Model of Russia”, St Petersburg https://grandmaket.ru/en/#promuseum It is the largest model in Russia (800 m²) showing cities and towns, forests, seas, people and animals, roads and railways. The exposition has all key and typical objects of every Russian region. You can see different scenes from the life of the country: moving trains and cars, naval base, spaceport, a shepherd with a flock of sheep, ships at sea, etc.

The exhibits are dominated by model recreations of St. Petersburg and Moscow, Russia’s largest cities. The St. Petersburg model looks particularly pretty when lit up “at night” when thousands of LED lights help simulate night turning into day. Wild weather events like storms and snow are simulated too. https://russiatrek.org/blog/photos/national-show-museum-grand-model-of-russia/ https://www.expedia.com/Grand-Maket-Russia-Interactive-Museum-StPetersburg.d6303715.Vacation-Attraction

ARTICULATED STEAM LOCOMOTIVES Meyer The Meyer was the brainchild of Frenchman Jean-Jacques Meyer. In 1868 the first locomotive, an 0-4-0+0-4-0 named L'Avenir (Future), was built by J. F. Cail et Cie. No wheels are rigidly affixed to the boiler; all are mounted on bogies placed directly under the boiler/cab unit. This compares with a Mallet, where the rear set of wheels are attached to the frame, and only the front set swivels as a bogie. Therefore, boiler overhang is less than that of the Mallet locomotive on a curve of the same radius. Meyers are usually set up as a tank engine, with the boiler/cab unit carrying the water and fuel supplies.

A disadvantage of the design is that the firebox is directly above the rear power unit, which limits its size. With two power bogies, flexible steam pipes must be provided to all cylinders.

This was difficult to achieve with 19th Century technology.

Meyer locomotives were most common in continental Europe, particularly Germany. A number of Meyer locos can still be found on the narrow gauge railways in Saxony. The most common locomotive is the Saxon IV K.

Kitson Meyer The Meyer design was modified by moving the rear power unit further back and allowed the firebox to be between the two power units (as in a Garratt), thus allowing a larger firebox. The length of engine was increased, with the extra length behind the cab being used for additional water tanks. Some designs had an auxiliary chimney at the rear to avoid the need for an exhaust steam pipe running the length of the engine.

Kitson Meyers were widely used in South America, particularly on the Colombian and Chilean railways. It was regarded as the best performing of all articulated designs for railway lines that constantly curved. However fewer than 100 Kitson Meyers were ever built, and it was generally thought that the design suffered from competition with the Garratt.

Mallet

The Mallet locomotive was designed by the Swiss engineer Anatole Mallet (1837–1919). Diagrams provided by Mallet make it clear that the swivelling truck was to be a Bissell truck, which is a pony truck or bogie pivoting about a vertical pin some distance behind the centre of the truck. The weight of the front part of the boiler was to be supported on an arc-shaped radial bearing. The truck could therefore turn into a curve and move to some extent laterally. Typically the support bearing was placed beneath the smokebox, hollowed and with a sliding seal to provide a route for exhaust steam from the lowpressure cylinders to discharge through a blastpipe within

the smoke box.

Mallet considered that the major advantage of this arrangement was that it enabled the cylinders on the truck to be fed with low-pressure steam: the high-pressure cylinders were on the fixed main frame and only low-pressure steam needed to be carried through movable pipes to the swivelling truck.

B&O No. 2400, the first American Mallet Mallet's original patent specifies compound expansion, but after his death in 1919 many locomotives (particularly in the United States) were articulated Mallet style without using compounding (for instance the Union Pacific Big Boy).

Large numbers of Mallet designs for narrow gauge railways were built and in 1889 the first six standard gauge units were built by J A Maffei for the Swiss Central railways plus an 87 tonne 0-6-6-0T banker for the Gotthard Bahn; the last being the most powerful and heaviest locomotive in the world at the time.

By 1892 110 Mallets were at work; by 1900 there were nearly 400. The biggest and heaviest examples built for European railways were the 0-8-8-0Ts built by Maffei for Bavarian State Railways between 1913 and 1923.

However no Mallet ever ran on a British railway.

Fairlie

A Fairlie has the driving wheels on bogies.

The locomotive may be double-ended (a double Fairlie) or single ended (a single Fairlie). Fairlies are most associated with the Ffestiniog Railway in Wales.

While the Fairlie locomotives are now only used on heritage railways, the vast majority of diesel and electric locomotives in the world today follow a form not very different from the Fairlie - two power trucks with all axles driven, and many also follow the Fairlie's doubleended concept, capable of being driven equally well in both directions.

Garratt A Garratt (often referred to as a Beyer Garratt) is articulated into three parts. Its boiler is mounted on the centre frame, and two steam engines are mounted on separate frames, one on each end of the boiler.

Articulation permits larger locomotives to negotiate curves and lighter rails that might restrict large rigidframed locomotives.

Many Garratt designs aimed to double the power of the largest conventional locomotives operating on their railways, thus reducing the need for multiple locomotives and crews.

FAMOUS LOCOMOTIVE – BEYER-GARRATT articulated steam loco built

by Beyer-Peacock, Manchester, UK. Patented 1907.

CP Lewis The Great Steam Trek p178 near Claridge KZN 1979 The Garratt articulated locomotive is attributed to be developed by Herbert William Garratt, a British locomotive engineer. It was first built by Beyer, Peacock and Company from Manchester.

Weight: 228T Tractive effort: 308kN

Axle load: 17T Overall length: 28.7m Max speed: 35mph (56km/h)

The Beyer-Garratt differs from a conventional locomotive in that its boiler is not directly over the engine (chassis, wheels and motion), instead the boiler (cab) is mounted on a sub frame which is slung between the two engine sets which are allowed to pivot making the wheel base less rigid. On the front engine (chimney end) sits the water tank and on the rear engine sits the fuel bunker (coal/oil/wood). As there are no wheels under the boiler it can have a large diameter and deep firebox and the whole boiler unit is more accessible than with a normal rigid frame locomotive. Each end unit can have as many axles as the curvature of the line permits; six or eight driving axles being the norm.

South African Railways was the largest user of the type not only on the Cape gauge but also on the 2’-0” narrow gauge (610 mm), with 400 units being supplied of several different classes; the largest class, numerically, was the GMA/GMAM with 120 being built, between 1952 and 1958, in batches shared between Beyer Peacock (58), North British (32) and Henschel (30).

10

A Beyer-Garratt with one crew can replace two double headed tender locomotives with two crews, e.g. one GM could replace two 19D tender engines with no loss in power output.

The geometry of the design allows the boiler unit to move inwards when traversing a curve and this reduces the centrifugal force allowing faster running.

The longitudinal spacing of the engine units gives a low figure for weight per foot run of wheelbase, permitting a Beyer-Garratt to cross restricted bridges of light construction and run on lightly laid track (60 lb/yard).

It is a good steam raiser, as a very large diameter boiler with a short length (thus short tubes) and large firebox can be easily incorporated as it is carried clear of all the parts of an engine such as wheels and motion.

Since the Beyer-Garratt runs equally well in either direction, turntables are not required.

On sections with many tunnels, where trailing smoke is liable to obscure the cab view or make the cab uncomfortable the engine can run cab first

South African Railways 2 ft (610 mm) gauge SAR NGG 16 Class Garratt, preserved in operating condition on the Welsh Highland Railway. This railway (like the Ffestiniog) uses articulated locos because of the tight turns on the line.

Beyer-Peacock built over a thousand Garratts, or Beyer-Garratts. The final Garratts to a Beyer-Peacock design were eight 2 ft (610 mm) gauge South African Railways Class NG G16 locomotives, built in 1967–1968. The order was placed with Beyer, Peacock and Co., but since the firm was in the process of closing down, it subcontracted the order to the Hunslet Engine Company. Hunslet's South African subsidiary, Hunslet-Taylor, in Germiston, built these locomotives using boilers manufactured by their mother company.

CLUB LIBRARY - TRACK PLANS

SHUNTING Inglenook Sidings, created by Alan Wright (1928 - 2005), is a model railway train shunting puzzle (US: model railroad switching puzzle).

It consists of a specific track layout, a set of initial conditions, a defined goal, and rules which must be obeyed while performing the shunting operations.

More broadly, in model railway usage inglenook or Inglenook may refer to a track layout (or portion thereof) that is based on or resembles the Inglenook Sidings puzzle.

"In December 1979, with the Manchester show approaching, my colleagues at work asked what I would be showing that year and when I said "nothing" I was taken to task and the next day one produced a blockboard off cut 4'0" by 1'0" and challenged me to build a railway on it and show it. Having some odd pieces of track and a couple of points Inglenook was born and the 5/3/3 formula was adopted. It was a roaring success at the show, I had the small controller on a six feet long lead and stood among the crowd listening to what they had to say and then carried out the movements they wished would happen. The aura of magic such operation produced made the crowd wonder if it was worked by someone watching on television or was it a computer?" http://www.wymann.info/ShuntingPuzzles/sw-inglenook.html

Alan Wright won an award with the model that year and later went on to build several layout variations on the Inglenook Sidings scheme.

The sidings should be able to accommodate 5, 3, and 3 wagons, the leading spur accommodating 3 wagons and the locomotive.

RULES & OPERATION The object of the Inglenook Sidings shunting puzzle is fairly simple, the order for the shunting crew being: "Form a departing train consisting of 5 out of the 8 wagons sitting in the sidings."

In addition (and this is where the "game element" of the puzzle comes in) the shunting order states: "The 5 wagons are selected at random."

Alan Wright employed what he called the "Tiddlywink Computer" for this task, i.e. distinct tokens for each wagon drawn from a mug. No matter how these 5 items of rolling stock are determined, the order in which this happens is important because: "The train must be made up of the 5 wagons in the order in which they are selected."

Fascinate visitors with a moving boat

A diesel locomotive with a magnet attached to its roof runs on a crossover oval track mounted to a wooden platform a few centimeters under a thin plywood lake surface. It pulls a small magnet attached to the underside of the boat dragging it in a figure 8 across the lake.
