Fig. 62.—Rock Island Southern Motor-car Train. Motive power from the central station is available for the ordinaryC- to 10-car train, the power supplied to which is usually larger than thatrequired by the electric locomotive hauled train. Rapid acceleration,which is so often desired, requires abundant motive power. 236 ELECTRIC TRACTION FOR RAILWAY TRAINS Terminal capacity is increased by more efficient train movements,absence of the locomotive turning, and rapid acceleration. ECONOMY OF OPERATION. Economy in transportation is of vital importance. It requires abilityto furnish capacity, speed, and unexcelled service; to induce traffic, toprevent complaint, to get business in competition, and to hold it, are alladvantageous, because business should be developed on a large scale tobe most profitable.

Fig. 63.—Salt Lake and Odgen Railway Motor-car Train. Economy of operation with electric motor-car trains is higher thanwith any other scheme of operation yet offered in railroading. Thishas been proved by results, and by use of such trains for the bulk ofthe suburban passenger train service from many large cities. The reasons for economy are grouped as follows: 1. Maintenance of ways and structures is less because of the distribu-tion of train weight, stresses, and motive power. 2. Maintenance of equipment is a minimum because of simplicity,lower cost of inspection, higher mileage, and higher rates of accelerationwhich allow a lower maximum speed. For comparison,—New York Subway in 1909 had 735 motor carseach equipped with two 240-h.p. motors, or an equipment of 350,000h.p. This would be equivalent to about 350 locomotives of 1000 h.p.each. Compare the small Interborough repair shop in use at the end ofits line with the tools, machinery and the men, the round houses, shop MOTOR-C
