An EMD SW9 is a diesel switcher locomotive built by General Motors Electro-Motive Division between January 1951 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 (895 kW). Starting in October 1953 a number of SW9s were built with the 567BC engine and in December 1953 Weyerhaeuser 305 was built with a 567C engine.

In addition, ten TR5 cow-calf paired sets were produced (eight for the Union Pacific Railroad, and two for the Union Railroad of Pittsburgh, Pennsylvania. The Union Railroad also bought an additional two TR5B "calves".

786 examples of this model were built for American railroads and 29 were built for Canadian railroads.


In 1994 Amtrak acquired nine SW9s from various railroads and had them rebuilt by the National Railway Equipment Company. These switchers were reclassified as EMD SW1000R.
