Postcard photo of Santa Fe's No. 1 engine after it was rebuilt post-1937. The locomotive is shown at the Fort Madison, Iowa, depot, pulling a seven-car consist. After serving as a paired set of boxcab locomotives hauling the Super Chief during 1937 (File:ATSF1 1935.JPG), the locomotive units 1a and 1b were separated, re-designated as Nos. 1 and 10, and rebuilt identically. Their twin cabs were replaced with one elevated cab at their head ends and the B trucks were modified with the addition of unpowered drop-equalizer axles (1-B). They gained the "war bonnet" paint scheme in use on Santa Fe's newest passenger locomotives.[1] They both served with the Chicagoan and Kansas Cityan day trains from 1938 to 1941. In 1941, No. 10 was rebuilt as a booster unit and rejoined with No. 1 to haul a larger consist. The pair served in that configuration until 1948, when No. 10 was removed and rebuilt as a freight transfer locomotive.
