December 1961. The Durango yard after a good snow. Note the red target on the switch stand. Normally red targets were used on mainline switches, yellow on yard tracks, and at the time this picture was taken this as just a yard track. But until about ten years prior it had been the mainline of the RGS into Durango, so I would guess the DRGW just never got around to changing the switch stands. As shown in another picture, the call board in the roundhouse office still showed the RGS. Things changed slowly on the ng.
