Swedish Diesel-Electric Motor Car of 250 Horsepo Diesel-Electric Motor Cars for Railway Service Successful Operation in Sweden Has Led tothe Introduction of 250-Horsepower Cars SWEDEN is one of the countries which is obliged to im-port its supply of locomotive fuel and consequently thegreatly increasing cost of coal is a serious factor inoperating expenses. An abundance of water power has madeelectrification practical on a number of lines where the trafficis heavy but this change is not feasible on a large amountof mileage where the traffic is relatively light. Both improve-ments in steam locomotives and the substitution of othersources of power are receiving thoughtful attention. Consid-erable pioneer work in the application of Diesel engines forrailroad motive power has already been carried on in Swe-den. The system favored uses a Diesel engine to drive anelectric generator which furnishes power to .motors mountedon the trucks. The first car, built in 1913, had a 7S-hp.engine. This
