SP NW2 page: 1965 system renumbering
1965 Renumbering:
In late 1965, the SP began a program to renumber the majority of its locomotive fleet into a consolodated system without regard for reporting mark. However, the SSW units did retain their identity, but the numbers were assigned within the overall scheme.
