Caption: An assortment of units at Tumbler siding. It was a busy spot with a large ground camp housing MoW personel, pusher crews and coal train crews as well anybody else on railway business. Eventually the pusher crews and coal train crews would layover in a new rest house facility in the town of Tumbler Ridge. Photo was taken in the vicinity of mile 61 Tumbler sub. I could not locate this area on the satellite map.
