SP SD7/9 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, two of which were the SD7 and SD9. All 43 SD7's and 144 of the 150 SD9's went through the program being rebuilt at Sacramento, CA by SP shop forces.
