On both Santa Fe branch derailments, the 470 pulled a work train of 9 loads and 2 empties. Photos by Bob Richardson show a 9 car work train in Alamosa consisting of the following:
OP Derrick
06063 Boom car for OP
04013 Kitchen car
04549 Tool car
04444 Block car
04426 Cable car
06092 Tie & wheel car
06051 Tie & rail car
0452 Sleeper
I am not sure what the 2 empties were, but I suspect they were a couple of cabooses.
