For example: North-Eastern Railway of England uses multiple-unit cars forfreight service. Each car is 55 feet long, has four motors, andhandles luggage, parcels, and fish. These cars are coupled into eitheran electric- or steam-driven train. Paris-Orleans Railway uses heavy motor cars, of the baggage-cartype, loaded with supplies and high-grade freight, to haul Fig. 54.—Hudson and Manhatten Railroad Motor 48 feet; seats 44; weight 35 tons; builder, Pressed Steel Car Company. Many American railways now employ motor-cars in trains to haulordinary freight, baggage, building material, and ore. Special motorcars, which carry theatrical scenery, express, milk, fruit, etc., are usedin a train, or to haul coaches in local service. New York Central Railroad for its New York terminal serviceuses 47 electric locomotives, of 2200 each, while there are 137motor cars, of 480 each. These motor cars haul 63 coaches. Eachmotor car weighs 53 tons and each coach weighs 41 tons. The motorcapacity of each motor-car train exceeds the motor capacity of eachlocomotive. In 1908 the locomotive mileage was 1,000,000 while themotor-car- mileage was 3,500,000. The importance of the motor-cartrain service is at once recognized. CHARACTERISTICS OF MOTOR-CAR TRAINS. The characteristics of electric motor-car trains are, in part, identicalwith those fo
