F20 - MagnumMacKivler/RLCPT2 GitHub Wiki
The EMD F20 was a cataloged locomotive by Electro-Motive that utilized the updated technology (such as turbocharged engine) as the GP20 while keeping the streamlined body look of the F series locomotives (such as the F9). The F20, along with the non-turbocharged F18 (based on the GP18), were never made.
Most railroads by the late 1960s had drawn away from passenger service, which likely would have been the only use for the hard-to-see-around F units. Specifications would likely be identical to the GP20 locomotive except for the carbody.
