PROTOTYPE AND BACKGROUND INFO

EMD F-units were a line of diesel-electric locomotives produced between November 1939 and November 1960 by General Motors Electro-Motive Division and General Motors-Diesel Division. Final assembly for all F-units was at the GM-EMD plant at La Grange, Illinois and the GMDD plant in London, Ontario, Canada. They were sold to railroads throughout the United States, Canada, and Mexico.

The EMD FP7 was a 1,500 horsepower (1,100 kW), B-B passenger-hauling diesel locomotive produced between June 1949 and December 1953 by General Motors’ Electro-Motive Division and General Motors Diesel. Final assembly was at GM-EMD’s La Grange, Illinois plant, excepting locomotives destined for Canada, in which case final assembly was at GMD’s plant in London, Ontario. The locomotive contained an auxiliary water tank and steam generator to supply steam heat to the trailing passenger cars. This necessitated a longer body and frame. Although intended for passenger service, these locomotive still were regularly assigned into freight locomotive pools as well.

When Amtrak began operations in 1971 they had to get used locomotives from the railroads rather than buy brand new ones. These included a group of FP7’s and F7B’s from the Southern Pacific and some F7B’s from Burlington Northern. They weren’t able to paint all of the SP’s FP7’s right away and just used simple patching on some units, like #118, to mark the units as Amtrak property. Some B-units, like #399, received the pointless arrow while others received simpler paint jobs.
