Southern Pacific/Cotton Belt
1973 Locomotive Roster

July 1st 1973


The Number Series, is the actual unit number of active unit(s).

There is a confusion over Baldwin model designations, not surprising considering Baldwin's tendency to change them. The DS44-1000 appears to cover a few model types, S-10 seems to be an SP only designation, and some are later listed as VO-1000's.

New model's to this Roster are in Red unless your Browser doesn't support it.

There is great confusion between the 'E' and 'R' designation appended to rebuilt units.
I have usually used the locomotive class as the basis for deciding whether to list the units as 'E's or 'R's. Some Rosters may still have inaccuracies in this regard.
Cotton Belt (SSW) units that have been rebuilt, are 'supposed' to have Southern Pacific lettering upon release, this may or may not be the case...
The SSW SW7 and SW9 rebuilds are listed variously as, SW7E, SW9E and SW1200E...
