Re: T-12 operation between Alamosa and Durango?

During the winter of 1932, one of the worst on the narrow gauge, eastbound rotary OY, along with the eastbound passenger train became snowbound near MP 321, about a mile west of the Cascade Creek trestle. The rescue involved both rotary OM and ON (from Salida). The section cars and other supply cars operated as a separate train pulled by 174 and 478. In going through the Cumbres train registers for the 1930's (these can be examined at the Colorado Railroad Museum Library) this in the only instance of a T-12 arriving at Cumbres that I have found for that time period. Details below.

February 16, 1932
Extra 174 West
Conductor Mason (caboose 0579)
174 Peterson
478 McClintock
496 Wellington (Originally on a westbound freight but transferred to rotary OM as a third engine. Released at Osier from OM as no longer needed and added to extra 174-478 rather than run it as a separate movement.)
Arrive Cumbres 8:30 AM, tied up 1:55 PM

February 17, 1932

Extra 174 East
Conductor Mason (caboose 0579)
174 Peterson
478 McClintock
496 Wellington
Depart Cumbres 1:35 AM, 10 minutes behind rotary ON.
(These two trains departed eastbound immediately after the arrival of the westbound rotary OM.)
