EMD F3

The EMD F3 was a 1,500 hp (1,100 kW) B-B freight-hauling diesel locomotive produced between July 1946 and February 1949 by General Motors' Electro-Motive Division. Final assembly was at GM-EMD's La Grange, Illinois plant. A total of 1,111 cab-equipped lead A units and 696 cabless booster B units were built. The F3 was the third model in GM-EMD's highly successful F-unit series of cab unit freight diesels, and it was the second most produced of the series. The F3 essentially differed from the EMD F2 only in power, and from the later EMD F7 in electrical equipment. Some later F3s had F7 traction motors, and were nicknamed F5 models.
