e expensiveitems, therefore, enter into theconstruction of a conduit road,namely, the deep excavation,which may call for the changing of other underground pipes orconduits in the street; the large amount of iron and steel neededfor the yokes and slot rails; and the large amount of concreteneeded. STEAM RAILWAY ELECTRIFICATION Applying electric power to steam railways may be done eitherby substituting electric locomotives for steam locomotives or byusing multiple-unit car trains, or both. As examples of steamrailways which are using electric locomotives in place of steamlocomotives on parts of their lines may be mentioned the NewYork, New Haven and Hartford Railroad, the New York Centraland Hudson River Railroad, the Pennsylvania Railroad, theGrand Trunk Railroad, the Erie Railroad, and others. The multiple-unit cars have been largely used on the LongIsland Railroad and they are used for suburban service in some ofthe others mentioned. Section of Underground ConduitShowing Handhole 351

352 ELECTRIC RAILWAYS 255 ELECTRIC LOCOMOTIVES Essentially the electric locomotive does not differ in principlefrom a small electric car. It consists of one or two trucks equippedeither with gearless or with geared motors. The motors and con-trol apparatus are so bulky that there is no room for passengers.This follows because the amount of power to be generated is somuch larger than in the case of small cars. The ordinary form of electric locomotive consists of a plat-form mounted upon two swivel trucks. The platform carries acab which, in small-sized locomotives, occupies a small space inthe middle of the platform. The cab contains controllers, measur-ing instruments, and some of the auxiliary apparatus. The re-mainder of the control apparatus is in many cases located undertwo sloping housings which cover the remainder of the platform.The general appearance of such a locomotive is shown in Fig. 243. Some of the details of the equipment of such a locomotiveare shown in Fig. 244, which
