Under threatening skies, the 315 Extra rounds the curves at Big Horn.

D&RGW 315 leads its train around the curve to the lowest of three levels at Whiplash. The highest can be seen in the background.

A look into the past as the conductor walks the roof, setting the brakes to hold the train on the steep siding while waiting on the late Moonlight Train.

A very rare moment on the San Juan Extension. Three trains were stopped at Osier for lunch, including the 315 Extra. Two are seen next to each other while the other departs for Chama.
