F7
The EMD F7 is a 1,500 horsepower 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 F7 was the fourth model in GM-EMD's successful line of F-unit locomotives, and by far the best selling cab unit of all time. In fact, more F7s were built than all other F-units combined. The F7 succeeded the F3 model in GM-EMD's F-unit series, and was replaced in turn by the F9.
