SP F-units page: 1949 renumbering

1965 Renumbering:

In late 1949, the SP began a program to renumber its growing fleet of cab and booster units which had been mostly delivered in four unit ABBA sets with each locomotive in a set given an alpha suffix. Other cab and booster units were included such as EMD E-units and ALCO PA & PB units, but are not included here. Neither T&NO nor SSW F7's ever carried alpha suffixes. Note that the SSW FT units were renumbered in a way such that the original "set" numbers used with the alpha suffixes were not re-used.
