Caption: The first Standard General aggregate train of the season rolls into St. Albert, bound for the processing plant in Acheson. This train only operates during the spring and summer months between the Silver Creek mine located west of Whitecourt and typically runs in a distributed power configuration, which helps with the shove move from Bissell to Acheson on the Edson Sub. Aggregates are a fairly lucrative business for CN in the Edmonton area with three different unit trains operating. The RROX set runs from a mine near Benbow, also on the Sangudo Sub to a plant at Clover Bar and the Cadomin trains run year round from the Mountain Park spur to Bissell.
