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 or GP7u designation to indicate a rebuilt unit.

Santa Fe began a program in its Cleburne, TX shops to rebuild GP7s. The program was started in 1972. The high short hoods were chopped down, dynamic brakes deactivated (if present) and in some cases new cabs were installed. The prime movers were upgraded with new components. The upgraded geeps gave long service and many lasted through the BNSF merger.
