Sometimes working NG, Sometime working SG D&RGW #633

This photo is of D&RGW engine number 633 which I wonder if someone could confirm is at Salida account of the 3-rail track has the standard rail on the east side of the narrow gauge. If it was at Alamosa the standard gauge rail was added west of the narrow gauge two rails.

This photo is additional interesting account of the diagonal slotted draft gear. The coupler is set for 23” above the narrow gauge rails but can move 10 1/4” to the right and upward to be 32.5” above the standard gauge rails to match the coupler height of standard gauge cars being 33.5” empty and 32.5” loaded with leeway of 1” each direction in each location. If this engine was used at Alamosa it would have to be facing north. I believe it is facing south in this image at Salida. Otto Perry photographed this locomotive with a boarded up cab in 1925 looking like it was heading to a new owner. CRRM roster of D&RG say it was former #573 and renumbered in 1924 to #633 and sold to San Luis Valley Southern as their #104 and dismantled in April 1944. It was built by Baldwin #9754 1889 and was a class C-28.
