Caption: 520 rolls out of Calder/Walker Yard in Edmonton and down the Wainwright Sub, toward Bretville Junction, where it will veer right down the Camrose Sub. It has grain empties for the elevators along the way and center beam lumber cars for a mill in Camrose. The buildings to the right were for the stockyards that thrived at one time in NE Edmonton. And the haze is likely smoke that blew in from forest fires.
