Caption: The day Sarnia yard job is done and heading back to the Depot (American terms here.. not a Station) to tie up for the afternoon shift. It's a foggy December day and you can really see the track condition on the three welded rail tracks that roll through the yard. While only one track is the mainline, all of this track was upgraded in the 1980's with welded rail and would soon host mainline trains with big power from Detroit for the better part of two decades. From left to right is Old Main, Track 1, Track 2, Track 3, etc.
