The EMD SW8 is a diesel switcher locomotive manufactured by General Motors Electro-Motive Division and General Motors Diesel between September 1950 and February 1954. Power is supplied by an EMD 567B 8-cylinder engine, for a total of 800 hp (600 kW). A total of 310 of this model were built for United States railroads and 65 for Canadian railroads. Starting in October 1953 a number of SW8s were built with either the 567BC or 567C engine.
