An EMD SW900 is a diesel switcher locomotive built by General Motors Electro-Motive Division and General Motors Diesel between December 1953 and March 1969. Power was provided by an EMD 567C 8-cylinder engine that generated 900 horsepower. Built concurrently with SW1200, the eight cylinder units had a single exhaust stack. 260 examples of this locomotive model were built for American railroads and 97 were built for Canadian railroads. Canadian production of the SW900 lasted three and a half years past EMD production. Seven units were exported to Orinoco Mining Co; two units were exported to Southern Peru Copper Co; and five units were exported to the Liberian-American Mining Co. Total production is 371 units.
