The first three decades of service.

The table below covers the period from original delivery of the class up until the rebuilds.  Certain members of the class survived into the BNSF merger; most of those are covered in Gene Crossett's SF Diesel Roster.  The class includes 5 cabless booster units, charted below.

Original Rooftop:
(click here for three examples)
at = rooftop air tanks & steam generators added by SF shops:
        2650-2654 in May-51 and 2848 in Apr-53.
db = dynamic brakes.
ds = dynamic brakes & factory-installed steam generators.
? = dynamic status unknown, presumed missing.
d? = dynamic status unknown, likely to have been present.
A condensed table of these characteristics is available:click here

Rebuilt to:
119 and 115 are yard slugs. These units have the cab & hoods
replaced with a single low shell, and work with 1310-class slug mothers.

1310-class units are slug mothers;
2000-class and 2050-class are "normal" units;
2244-class units are upgraded to GP9.

Cab Style as rebuilt:
rc = original round cabs retained in rebuild.
ac = angled "Topeka" cab with air conditioner.

Disposed:
wrk = wrecked; T/unit type = traded on unit type.

Other notes:
r = received pre-merger "Kodachrome" livery around 1986. (See 2126 here.)
