As a follow up to its successful introduction of the FT, EMD made a few improvements to the design and offered its 1,350-horsepower F2 which was essentially an FT in a new body. The F2 was produced for only a few months, but its new body would become the basis for thousands of F series diesels to follow. Its successor, the 1,500-horsepower F3 offered customers a boos in power along with numerous internal changes to improve performance. In addition, the F3 was touted as a dual-service locomotive that could handle freight or passenger runs (when equipped with a steam generator). Offered as A units or as cabless B unit boosters, EMD went on to build over 1800 units between 1945 and 1949 when the F3 was succeeded by the F7.
 
In service, F3s were assigned to mainline freights and fast passenger runs. The units were reliable and helped many railroads make the switch from steam to diesel. The locomotives were also versatile because they could be used in matched consists or with other locomotives with multiple-unit connections. They were also long lived, with the last F3s pulled from regular freight service in the late 1980s and numerous others preserved in museums.
