The EMD F7 is a model of 1,500-horsepower (1,100 kW) diesel-electric locomotive produced between February 1949 and December 1953 by the Electro-Motive Division of General Motors (EMD) and General Motors Diesel (GMD).

The All-American F7 defined railroading during the 1950s; nearly every notable Class 1 operated at least one and many rostered dozens, or even hundreds, of these locomotives. When one pictures Electro-Motive's classic streamlined diesels, the F7 most often comes to mind.

EMD F-units are a line of diesel-electric locomotives produced between November 1939 and November 1960 by General Motors Electro-Motive Division and General Motors-Diesel Division. Final assembly for all F-units was at the GM-EMD plant at La Grange, Illinois, and the GMDD plant in London, Ontario.

Jul 6, 2006 · The F7 sold 3,849 units (2,366 A’s, 1,483 B’s) in North America during 1949-1953, the height of the dieselization of American railroads. In U.S. diesel history, only two other models, both also EMD, the GP9 and the SD40-2 have outsold the F7.
