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. One cosmetic difference separating the two locomotives was the two 48? fans on late production GP-9s to replace the four 36? fans found on the GP-7 and early GP-9s.
