Caption: It is currently +31 in Edmonton, but soon the weather will turn and scenes like this will be common again. The GTW Heritage unit leads Edmonton to Cadomin stone train U 72552 25 past the one mile to station sign at Mercoal, on the isolated Mountain Park Spur. It turned out that the line was tough to chase, with very few access points, however it was a nice drive along Forestry Trunk Roads on a warm February morning.
