Caption: After switching out Frames with Modatek and Gons from Karmax on the Glass Lead, CN L551 re-enters the mainline and continues eastward on the Halton Sub North track just past Milbase to switch out a few boxcars with Westrock (seen just behind the tail end of the train). Once completed, they continue eastward (seen in photo) to Spot loaded tanks and pull empty’s from Recochem before running around their train and returning to Aldershot after dark. The switch into Whirlpool Canada (switch seen on the south track in the photo’s foreground) has been clamped for the main as they do not receive cars anymore.
