The EMD SW7 was a diesel switcher locomotive built by General Motors Electro-Motive Division between October 1949 and January 1951.[2] It was powered by a 1,200 horsepower (895 kW)12-567A engine.[1] The SW7 replaced the earlier 1,000 horsepower NW2 switcher in EMD's catalog.[3] A total of 489 SW7 locomotives were produced. The majority of the SW7s were built by EMD Plant #3 in Cleveland, Ohio.[citation needed] In addition, 15 TR4 cow-calf paired sets were produced.[3]
SW7 production was discontinued in 1951 in favor of the new SW9.[2]
