SP GP35 page: GRIP Program

GRIP Program:

The SP began a large scale program to rebuilt its many locomotives called the GRIP (General Rehabilitation and Improvement Program) in 1970. It encompassed many models of locomotives, one of which was the GP35. A total of 6 GP35's went through the program being rebuilt at Sacramento, CA by SP shop forces. Another 2 groups of GP35's were rebuilt by either Morrisson-Knudsen or the Canadian National raiload. The in-house rebuilt units lost their factory turbochargers and were derated to 2000 hp, except for the SP 6300. All rebuilt units received full rear gyralight packages.
