An EMD SW900 is a diesel switcher locomotive built by General Motors Electro-Motive Division and General Motors Diesel (GMD) between December 1953 and March 1969. Power was provided by an EMD 567C 8-cylinder engine that generated 900 horsepower (670 kW). 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 (Venezuela); 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. Some SW900s were built with the generators from traded in EMC switchers and were classified as SW900M by EMD. These units developed 600 or 660 horsepower with the older generators instead of the full 900 horsepower of the SW900. In the early 1960s, the Reading Company sent 14 of their Baldwin VO 1000 model switchers to EMD to have them rebuilt to SW900 specifications. The Reading units retained the Baldwin switcher carbody and were rated at 1000
