Beautiful pics Matthew. A good time to hike since the bears are all in hibernation!
The situation there seems similar to Rogers Pass on the Canadian Pacific in British Columbia. Coupled with their Albert Canyon and Eagle Pass sections, I think they originally had 53 wood sheds. Most of these were eliminated with the Connaught Tunnel, although concrete sheds still exist in Albert Canyon. The only two wood sheds I’m aware of are on the shore of the lake at Three Valley Gap west of Revelstoke, and plainly visible from the lodge there.
Cheers,

PS. In these days of social distancing, exploring abandoned lines remains an acceptable activity I gather!
