"A Winter Morning at Yoho "

On the lower slopes of the valley between the spiral tunnels sat the little station at Yoho. Moments after the passing of a westbound train on the near track, this eastbound starts slowly out of the siding under clouds of white exhaust.

The station operator and his dog watch the proceedings, as does the brakesman at the east switch. The train will shortly enter the upper spiral tunnel, and will then cross the picture from right to left along the faint line through the trees in the lower background.
