The EMD SW9 is a model of diesel switcher locomotives built by General Motors Electro-Motive Division between November 1950 and December 1953. Additional SW9s were built by General Motors Diesel in Ontario Canada from December 1950 to March 1953. Power was provided by an EMD 567B 12-cylinder engine, producing 1,200 horsepower. 786 examples of this model were built for American railroads and 29 were built for Canadian railroads. The SW9 was EMD's successor to the SW7. Like the SW7, the SW9 retained a power output of 1,200 hp and the same general design. |
