EMD SW7

The EMD SW7 was a diesel switcher locomotive built by General Motors Electro-Motive Division between October 1949 and January 1951. It was powered by a 12-567A engine. The SW7 replaced the earlier 1,000 horsepower NW2 switcher in EMD's catalog. A total of 489 SW7 locomotives were produced. The majority of the SW7s were built by EMD Plant #3 in Cleveland, Ohio. In addition, 30 TR4 cow–calf paired sets were produced.

SW7 production was discontinued in 1951 in favor of the new SW9.
