The F7 was the fourth model in GM-EMD's successful line of F-unit locomotives, and by far the best-selling cab unit of all time. In fact, more F7s were built than all other F-units combined. The F7 succeeded the F3 model in GM-EMD's F-unit series, and was replaced in turn by the F9.
The locomotive is an EMD F7A built in 1950, and used in service by the Kansas City Southern Railway until 1991, although it was converted to a slug unit sometime in the 1970s and the body was filled with concrete and old wheels.
The FT, introduced in 1939 with the new 1,350 hp (1.01 MW) 567 engine and Blomberg B trucks, was a successful design, and remained in production during WWII.. The F3 (1946) had a different roof arrangement that included the replacement of the FT's boxy dynamic brake structure with two under-roof grids, two exhaust stacks instead of four, and four cooling fans grouped together instead of ...

Minimum site dimensions were dictated by the distance and geometry required for the high-speed trains under development to reach their top speeds of 250 to 300 mph (400 to 480 km/h); the minimum specified radius of curvature was 2.5 mi (4.0 km), making the planned test track/guideway oval approximately 5 mi × 8 mi (8.0 km × 12.9 km).
The design was based on the Electro-Motive Diesel EMD F7 locomotive. [1] The first 11 were delivered with EMD 16-567B , 1,119 kW (1,501 hp) engines and four powered axles with the remainder having 16-567C, 1,305 kW (1,750 hp) engines and six powered axles.
