AN ELECTRIC EXPRESS LOCOMOTIVE on the Austrian Federal lines. The engine, 1670 class, has independent axle drive, and the wheel arrangement is 2-8-2. The railway uses single-phase alternating current of 16 cycles, 15,000 volts at the contact line. There are at present 215 electric locomotives in operation on the Austrian Federal Railways.

ELECTRICALLY HAULED. A heavy freight train on the mountainous Mittenwald line. Extensive electrification has been the post-war policy of the Austrian Federal Railways, and to-day some 571 miles of route are electrified. In one year the railways in Austria carried over 19,200,000 tons of goods.

A MODERN AUSTRIAN LOCOMOTIVE with an unusual wheel arrangement known as the reversed "Mountain" or 2-8-4 type. The bogie is specially placed at the rear of the engine to support an extra large firebox.

EUROPE'S MOST POWERFUL GOODS ENGINE. This is the claim made for the large freight engine, seen here on its arrival in Moscow in January, 1935. It was designed for hauling coal trains of 3,000 tons from the Donetz mines to Moscow.

OIL-BURNING LOCOMOTIVES, by the engine sheds at Kavkazskaya Station. There are some 20,000 steam locomotives and twenty Diesel engines at present in operation on the lines of the Soviet Union Railways

SIDE-TIP WAGONS unloading spoil during the reconstruction of the Donbas-Moscow line, on which the gradients have been reduced and a second track added.

FUTURE DEVELOPMENTS are foreshadowed by this electric train which runs along on balls instead of wheels. This novel device was the idea of a young Soviet inventor. Experiments are reported to have given satisfactory results. The picture shows the experimental track.

ON THE MOSCOW-LENINGRAD ROUTE. An express train on the main line, which is practically straight and level throughout. The greatest gradient is a twenty-miles section at 1 in 1,660. The "October Express," one of the best Russian trains, covers the journey of 404-1/2 miles between the two cities in ten hours, calling at Tver and Bologoe.

"ATLANTIC" TYPE express engine of the North Eastern Railway, as rebuilt by the L.N.E.R., with booster-driven trailing bogie partly under the tender. The auxiliary two-cylinder booster engine can be employed or cut out at will. The locomotive is therefore of the "temporarily articulated" type. This is one of the few locomotives whose wheel arrangement cannot be described by the standard system.

MODERN "BEYER-GARRATT" articulated engine of the 2-6-0 + 0-6-2 type, hauling a coal train on the L.M.S. line. "Beyer-Garratt" locomotives are used for handling the heavy mineral traffic between the Nottinghamshire coalfields and the marshalling sidings at Cricklewood, London, over the Midland route. Thirty-three of these efficient locomotives have been built for the L.M.S. since 1927.

A POWERFUL TANK ENGINE of the 0-6-2 + 2-6-0 "du Bousquet" articulated type. There are two rear high-pressure cylinders, and two forward low-pressure cylinders, placed back to back. The driving wheels are 4 ft. 5 in. in diameter. The tractive force is 45,050 lb. when working compound, and 49,170 lb. when working simple. This unusual engine works on the standard gauge Pekin-Hankow Railway, China, and was built in Belgium in 1906.

THE WORLD'S STRANGEST STEAM LOCOMOTIVE, the first of the new "Franco" articulated type, on test in Belgium. The main central unit houses two boilers and fireboxes and the compartments occupied by the driver and his two firemen. The engine has the unusual wheel formula of 0-6-2 + 2-4-2-4-2 + 2-6-0.

"SHAY" GEARED LOCOMOTIVE, Canadian Pacific Railway. This 4-4-4 type articulated engine has one pivoted truck under the fore part of the boiler and two others under the cab and tender. In front of the cab, on the right-hand side, is a three-cylinder vertical engine, which turns a flexible shaft geared to all the wheels. Locomotives of this type can ascend gradients of exceptional severity at low speeds.

THE FAMOUS TRIPLEX "MALLET," "Matt H. Shay," of the Erie Railroad, U.S.A. Once the largest locomotive in the world, this engine of the 2-8-0 + 0-8-0 + 0-8-2 type, can haul loaded freight trains over a mile long. The diameter of the six cylinders is 36 in. and exceeds the length of the piston stroke, which is 32 in. The rear pair of cylinders exhausts into an auxiliary chimney, seen at the back of the pseudo-tender.

A MODERN EXAMPLE of the "Mallet" type of semi-articulated locomotive. It is used on the metre-gauge Burma Railways, and has the 0-6-0 + 0-6-0 wheel arrangement. The working steam pressure is 180 lb. per sq. in., total heating surface 1,442 sq. ft., and the diameter of the driving wheels 3 ft. 3 in. There are two 15-1/2 in. diameter high-pressure cylinders, and two 24-1/4 in. low pressure cylinders, with a common piston stroke of 20 in. The tractive force at 50 per cent of the boiler pressure is 22,170 lb., and the service weight of the engine and tender is 95-3/4 tons.

AN ARTICULATED TANK LOCOMOTIVE, one of three 2-8-0 + 0-8-0 "Kitson-Meyer" type engines belonging to the diameter, cylinders (4) 14-3/4 in. by 24 in., and working pressure 180 lb. per sq. in. The weight in working order is 101 tons, and the tractive effort at 75 per cent of boiler pressure is 29,322 lb. The gauge is 5 ft. 6 in.

JAMES SPOONER" a typical double-boiler "Fairlie" type engine of the 0-4-0+0-4-0 type, belonging to the Festiniog Railway, North Wales. The curves on this 1 ft. 11-1/2 in. gauge line are extremely sharp. The engine-driver stands on one side of the single, long firebox, while the fireman stands on the other side. There is a rigid wheelbase of 4 ft. 6 in., and a total wheelbase of 18 ft. 8 in. The weight in working order is 20 tons 1 cwt. "Fairlies" are chiefly used on narrow-gauge systems.
