Caption: CN L538’s first assignment of the day on the Valleyfield is to drop off 50 empty Acid Tankers at the side track (Track V041), before they go down the CIL Spur where they’ll work National Silicates, and Goodyear. Here they are seen pulling past the switch, where soon the conductor will unhook the 50th Acid tanker, then she’ll line the switch to track V041, where 538 will back up into that track, then drop off the tanks, before they continue to the CIL Spur.
