GP40 No. 3072

As of May 1999


This photo shows No. 3072 in Alamosa, CO, 5/14/1999.  By this time it was not rated to lead trains-- it was configured as a "B" unit-- and was buried in the consist.  It would be retired exactly a year after this photo, May 15, 2000.

  • Most earlier GP40s had an additional engine room vent added by the railroad after delivery, forward of the dynamic brake fan.
  • Rio Grande locomotives delivered before 1980 came with the Nathan M3 air horn, but some were replaced over time.  The Leslie bells (shown here) are longer.
  • GP40 Nos. 3051 through 3075 were downgraded to "B" unit status in 1972.  When that happened, most cab amenities such as sunshades were removed, as well as speed recorder cables.   However, some of these units were later upgraded (during the SPL era) to be able to lead trains (promoted to "A" unit status).  This unit has sunshades, so it is possible that it was one of the upgrades.  At time of this photo, it had again been downgraded by UP to booster status.
