Description
In 1949 EMD unveiled the GP7, a general-purpose road-switcher that was suitable for a variety of tasks on the railroad. The GP7 went through several production variations, known as “phases” by railroad enthusiasts. “Phase II” units were typified by the addition of a box on the walkways on the fireman’s side, as well as the (optional) addition of dynamic brakes. This undecorated release is a good option for do-it-yourself modelers or freelancers, and comes with a selection of common, optional detail parts as well.

PROTOTYPE AND BACKGROUND INFO:
In 1949, EMD introduced the GP7. The basic design followed most diesel switchers with the addition of a short hood instead of an end-cab. The hoods were also full height to better accommodate the diesel engine and mechanical and electrical components.
Many railroads chose to rebuild their GP7s and GP9s for continued service. Often times, it was cheaper to do this rather than purchasing brand-new locomotives. Some railroads adopted a GP7R designation to indicate a rebuilt unit.
