In searching through the newspaper archives at the University of Oregon for Sumpter Valley stuff, I ran across this:

11 Passengers Stalled with Mountain Train
Den. Nov 23- A rotary snowplow was bucking huge drifts today in an attempt to reach a Denver & Rio Grande Western passenger train stalled near Cumbres Pass on the Contenintel Divide.
11 passengers on the train were thought to be in no immediate danger. The train runs over the narrow gauge line of the D&RGW between Alamosa and Durango.
