The EMD F2 was a freight-hauling diesel locomotive built by General Motors Electro-Motive Division between July 1946 and November 1946. It succeeded the FT model in GM-EMD's F-unit sequence, and was replaced in turn by the F3. The F2 was in many respects a transitional type between those two; it kept the 1,350 hp (1,010 kW) rated D8 generator from the FT due to late development of the new D12 generator intended for the F3, but in a revised carbody design and internal layout that would be continued through the rest of the F-unit series. 74 cab-equipped lead A units and 30 cabless booster B units were produced.
