Atlas Master Series Silver N Scale GP-7/9TT Locomotives

Atlas Master Series Silver N Scale GP-7/9TT Locomotives
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 substituted for part of a set of cab units. The GP-9 utilized a 1750hp engine and was visually similar to the GP-7.
