Introduced in 1949, the Electro-Motive 1500hp GP-7 combined the machinery of the F7 with a hood-type carbody that offered high visibility and easy
engine access. The GP-7 was used in pulling every conceivable type of train and was sometimes substituted for part of a set of cab units. The GP-9
utilized a 1750hp engine and was visually similar to the GP-7.
