Caption: Dashing through the falling snow and kicking up a trail of the white stuff behind, CN M636 2316 leads a sister M636, a C630M, and some GP40 widecabs on train #432, heading timetable west on the Grimsby Sub bearing down on Battlefield Creek (near Lake Avenue North) in Stoney Creek.

An errant dog, possibly belonging to the photographer Bill McArthur (or another spectator present) heads the same way, likely wise or scared enough of the barking MLW and GMD power rapidly advancing to make a hasty retreat back to their owner.
