At the time of writing the longest continuous electrically operated journey possible in Europe is over the 529 miles from Geneva to Salzburg via Zurich and Innsbruck by the Swiss Federal and Austrian Federal Railways. The distance is a little more than that from London to Aberdeen by the East Coast Route.
By 1937 it is hoped that electrical operation will be continuous from Paris for 512 miles to the Spanish frontier at Irun. The distance of 219 miles from St. Pierre-

Although by 1940 the percentage of electrified route miles in Europe will be relatively small, it should be realized that the lines electrified are among the most densely loaded lines. The electrified railways linking Rotterdam, Amsterdam, and The Hague handle a very high percentage of the total traffic in Holland. In Austria the lines connecting Vienna with the frontiers are those which are electrically worked; while in Hungary the Budapest-

ONE OF THE WORLD’S FASTEST ELECTRIC LOCOMOTIVES. This E04 class locomotive, hauling a train of seven corridor coaches, attained a speed of 94 miles an hour on its test run. The engine was built by the Allgemeine Elektrische Gesellschaft for the German State Railways. The Reichsbahn have over 930 electric locomotives in operation.

The map indicates the extent of the Swedish State Railways schemes. An important factor behind electrification was the increase in the speed of travel to the Continent via Malmo. To the student of railway economics the Swedish State Railways scheme is of special interest. When the plans were laid in 1920 for the electrification of the first 310 miles, the price of imported locomotive coal was over £6 per ton. This high cost of coal constituted the basic reason for electrification. The experts consulted by the Swedish Government agreed that the price of coal would probably fall to about £2 15s. per ton. In 1930 and 1931 the price fell to between 16s. and £1. Nevertheless, because of the success of the existing electrified section in attracting traffic and lowering operating costs, an extension of a further 560 route miles was put in hand in 1932. In general the railway electrification schemes have proved of the greatest possible value to Sweden in the stimulation of employment and the virtual avoidance of the effects of industrial depression on the railways.

After much discussion it was decided that one type of locomotive should be used for all purposes on the Swedish State Railways. This decision, of course, has helped to reduce operating costs. The locomotive has three driving axles, one guiding axle, and motors totalling 1,600 horsepower. In changing from express to freight traffic, a differential reduction gear is used between the driving motors and jack-

In Denmark electrification has been confined to the Copenhagen suburban area. The first part of the electrification scheme was finished in 1934, and this has proved so successful that an extension is now nearly completed. A British firm has been responsible for all the control and traction equipment of the first scheme and is supplying control equipment for the extension, as well as the designs and specifications for the traction motors, which are being made in Denmark.

Apart from a few small electrification schemes on privately owned railways, the German Reichsbahn (State Railways) electrification schemes fall into six as yet unconnected sections. The electrified mileage of these sections amounts to about 1,300 route miles, of which eighty-

The two European countries with the largest amount of total railway track converted to electrical operation are Italy and Switzerland. In Switzerland all the main lines and the great majority of the branch lines are electrically worked. Over ninety per cent of the country’s traffic is now operated in this way. Long, continuous gradients of 1 in 37 to 1 in 40 are common on the main lines. The latest locomotives are capable of hauling 600-

Early in the present century the water resources of the Pyrenees were developed for supplying the electrochemical industry, and the Midi Railway Company seized on the advantage of cheap power to begin its extensive schemes. The Pyrenees region gives an excellent example of the benefits which may be derived from the joint development of electrified industry, agriculture, and railway traction. To-

Since the war the rise of the electrical manufacturing industry in Great Britain has been remarkable, and no field of activity illustrates this achievement better than does railway electrification. In the British Dominions, of course, it was to be expected that British manufacturers would carry out the extensive schemes put into operation in South Africa, Australia, and India. In South America and Japan British workmanship has played a far larger part than that of any other country.

The fact that the electric locomotive draws its power from a central source is also responsible for the capacity of the electric locomotive to maintain speeds with heavy loads up steep gradients. It is this aspect of electric traction which has resulted in the conversion from steam to electricity on many of the European main lines. On the Swiss Federal Railway system, for instance, it was found in 1932 that the average haul of a steam train on certain sections of a line was limited to 132 tons, while, at faster running schedules, the average haul of an electric train was 310 tons.
