EMD SD9

Common card · No. 421636

The EMD SD9 is a model of diesel locomotive built by General Motors Electro-Motive Division between January 1954 and June 1959. An EMD 567C 16-cylinder engine generated 1,750 horsepower (1.30 MW). Externally similar to its predecessor, the SD7, the SD9 was built with the improved and much more maintainable 567C engine. 471 SD9s were built for American railroads, while a further 44 were produced for export. Many SD9s, both high and short hood variants, can still be found in service today on shortline railroads and with industrial operators. Although most Class I railroads stopped using these locomotives by the 1970s and 1980s, some remain on major Class I railroads in rebuilt form, as switcher locomotives.
