During the 1970’s, SP went on an ambitious task to rebuild their GP9 fleet, known as the “GRIP” program. This program included new wiring, new main generator, complete rebuild of the prime mover with new parts, improved battery box doors, and removed rear light packages (in some cases). A small batch of GP9’s were renumbered into the 2868-2899 class. Demoted to “switchers” in order to save maintenance costs, this class included rebuilt and non rebuilt units.

We are offering #2873, which retained it’s full light package on both ends. #2873 currently enjoys it’s retirement at a Northern California museum. It may be the last locomotives in this scheme still operating. Out of the large batch of SP GP9E’s, only 9 were painted into these colors.

PROTOTYPE SPECIFIC INFORMATION
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.

In 1954 EMD upgraded the GP7 to become the 1,750 horsepower GP9. Externally, the first GP9s were virtually unchanged from the last GP7s. Later versions would include different louver arrangements and the last ones would come without the frame skirting. The GP9 was available with all of the fuel tank, steam generator, and dynamic brake options as the GP7, including “torpedo tube” air tanks mounted on the roof.

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.
