GP40 No. 3077

As of December 1988


This photo shows No. 3077 leading the eastbound Railblazer on 12/24/1988.   UPDATE: I found the negative, and this image is a fresh scan (better color, higher resolution).

Rio Grande's GP40s came in several groups, as shown in this table.

 (1) Mars Light on low nose

(2) Replacement air horn-- looks like a Leslie instead of the Nathan M3 air horn

(3) Sinclair antenna

(4) Extra roof vent

(5) Cab sunshade

 

  • GP40s of this class were all delivered with the Mars signal light.  Some were later replaced with Pyle lights as maintenance required it, since Mars later went out of production.
  • Rio Grande locomotives delivered before 1980 came with the Nathan M3 air horn.  The bells on the Leslie are longer.
  • Most earlier GP40s had an additional engine room vent added by the railroad after delivery, forward of the dynamic brake fan.  It's blurry in this photo, but it's there.
  • GP40 Nos. 3051 through 3075 were downgraded to "B" unit status in 1972.  When that happened, most cab amenities such as sunshades were removed.  No. 3077 was not one of these.  Some units were upgraded back to lead unit status, and a few did not receive shades at that time. 
  • Note the lifting rings (eyebolts) on the roof.
