SP SD7/9 page: 1965/1973 Renumberings
GRIP Program:
The SP embarked on a renumbering plan to place all units into a unified numbering system late in 1965. The program continued well into 1966. Not all units were assigned new numbers such as the remaining F units which were not considered to be around more than five more years or so. The SD7 fleet was unique in that it was renumbered again in 1973 to make room for arriving MP15DC/AC switchers which were to be numbered in the SP 2700's.
