Here is the next to last shot from the Harrison photos in our SVRR Archive. This was taken at Chama, NM. on the DRGW narrow gauge in Oct. of 1967. We are looking west, so with the sun coming from that direction I assume it was taken in the late afternoon. Looks like all four engines are under steam. My guess is that the engine behind #497 is #487 since other photos showing the two together at Durango getting ready for a run east bound.
