In Central Europe

Many important new railway systems came into existence after the war of 1914-1918. Two of the most important are those of Czechoslovakia and Yugoslavia. The major portion of the Czechoslovak railways was formerly under the control of the State Railways of the Austro-Hungarian Empire. Since the war the policy of the Czechoslovak railways has been to improve main lines, and to afford better international communications. Electrification has also been carried out, and more is planned. The Czechoslovakia State lines conveyed some 220,000,000 passengers in 1933. The State Railways of Yugoslavia have overcome many difficulties, some of them unconnected with the railways themselves. The railways of Yugoslavia are also described in this chapter.

British Express Locomotives

The year 1935 has been one of the most eventful years in the history of railways. There have been developments vital to the future of rail transport. On March 5 the LNER steam locomotive “Papyrus” attained a speed of 108 miles and hour; later, a streamlined engine in Germany touched a speed of 119 miles an hour; then came a host of startling time-table accelerations in the USA. In Europe there has also been a reduction of schedules, and an increase of super-speed rail-cars. In Great Britain the large number of runs at over sixty miles an hour was greatly augmented. The new LMS turbine-driven express locomotive marked a significant advance; finally there was the record-breaking streamlined train “Silver Jubilee”, which was described in part 45. The rapid progress has been due to the steady improvement in the tractive effort of the modern locomotives - especially in Great Britain. This chapter includes a thorough survey of the notable classes of each of the four big systems and will contain a comprehensive table showing the chief dimension of the principal classes of British express engines in use to-day.

Spain and Portugal (Part 1)

The systems of one of the older European countries, Spain, are representative of modern influence upon that ancient nation. Some misinformed people believe that Span has not advanced with the times. But this chapter disproves this statement. A nation’s railways are a guide to a nation’s progress or decline. This chapter shows that an excellent service is offered to-day by the various companies. In countries as mountainous as Spain and Portugal narrow-gauge lines might be expected, but the main gauge is, on the contrary, very broad - 5 ft 6 in - and only to be found elsewhere in India and the Argentine. The main routes through Spain are particularly interesting. The railways in that country began in 1848. By the end of the nineteenth century, the mileage of track open totalled some 8,000. To-day it is over 10,000. One of the chief Spanish railways is the Northern, which owns some 2,300 miles of broad-gauge track, besides a large mileage of metre-gauge track. This company operates the most important trunk line from Madrid to Irun on the French frontier. Further, the Northern has followed a policy of electrification, and some of its most difficult sections are worked by electrically-hauled trains. There are no through expresses between Paris and Madrid, because of the break of gauge. One of the busiest links between France and Spain, however, is Irun, which connects with Hendaye on the system of the Paris-Orleans-Midi system.

The total railway mileage in Portugal is about 2,130, and of this total over 1,500 are controlled by the Portuguese Railways Company, and the remainder by smaller companies. The gauge of the Portuguese railways is the same as that of the Spanish, 5 ft 6 in. This system too is included in this interesting chapter. The article is concluded in part 47.

Locomotive Accessories

This chapter describes one of the most important items of a railway engine’s equipment - the injector, which supplies water to the boiler. Invented in 1859 by Frenchman, Henri Giffard, it now forms a vital part of the modern engine. The action and use of the donkey-pump, the feed-water heater, the soot-blower, the steam-blower, and the ”booster” will also be clearly explained. The “booster” is one of the most interesting locomotive accessories. It is a small auxiliary engine which drives one or more pairs of wheels on the engine or tender. The “booster” is employed chiefly to give extra power when starting exceptionally heavy trains, and has been installed on several big American and on some British locomotives. This is the seventeenth and final article in the series on Design and Invention.

You can read a useful technical summary of the steam locomotive injector in George Nissenson’s treatise (1890).

A Combined Pump and Heater

A COMBINED PUMP AND HEATER for the boiler feed water fitted by Messrs. J. Stone, Ltd., To a “Beyer-Garratt” locomotive on the Kenya-Uganda Railway. The water is heated by means of tubular heaters which are placed on top of the boiler. The pump, with its valves, is situated at the side of the boiler, and is controlled from the locomotive cab. To the left of the feed-water heater pump is shown a small steam turbine and electric generator for supplying current to the headlights at either end of the engine. To the left of the feed-water heater is seen the dome from which steam is taken to the cylinders, and to the left of this again are the clack valves through which water is supplied to the boiler. Against the smoke-box can be seen the Westinghouse pump for supplying compressed air to the brake system.

The cab illustrated is of a “King” class locomotive, and so this photograph complements

the frontispiece.

The Chicago Underground Freight System

600,000 TONS of package freight are handled every year by the Chicago underground freight system. Tracks for tunnel trains are laid also in railway warehouses, and tunnel trucks are conveyed up from below by elevators. This helps to reduce congestion in the streets of the city.

The Chicago Underground Freight SystemA modern injector

A Modern Injector

A MODERN INJECTOR is shown in this illustration, and the compact design of this important auxiliary to a locomotive is clearly indicated. Steam is taken to the top of the long casting at the right. On the left of the steam inlet is the cock controlling the water supply. Beneath the water cock is the flange to which is bolted the overflow pipe. The flange at the bottom of the main casting, on the right, is bolted to a pipe delivering feed water to the boiler.

A feed water heater

A Feed Water Heater

FEED WATER is heated by means of this apparatus (shown left), which is bolted in duplicate to the top of a locomotive boiler shell. The flange on the left is bolted to the water supply pipe from the injector or pump. On top of the fitting can be seen the adjusting screw which controls the lift of the clack valve. The right-hand flange is bolted to the boiler barrel, and immediately beneath this can be seen the openings to the two cones . The feed water is delivered to the boiler through the out-turned opening shown.
