On a partly sunny day, a westbound 351 (and not the only one that day) overlaps itself on the way to Vancouver during the beginning of fall in the Rockies. At this point, the westbound train is headed geographical east, looping around in the Kicking Horse valley to drop elevation manageably before going around the slopes of 10, 495' Mt. Stephen, the peak seen in the background. This grade is 2.2%, where the original temporary grade was 4.5% straight up to the pass. Another alignment was surveyed that would have gone through a long tunnel in Mt. Stephen's flank, but that idea was eschewed and instead the CPR built swiss-style tunnels that looped over themselves to increase the distance the train travelled. It's hard to see with all the recent tree growth, but the train is visible just above the shack to the right of the second locomotive.
