Caption: It's 2 PM and I left Sarnia in the afternoon to see if I could find the northbound freight from Chatham. I found them around Sombra, but my chase was very brief as it only lasted two crossings. Pictured they are passing one of the many concrete mileposts (and whistleposts) that still dot the landscape on the Sarnia sub all the way to Blenheim. Due to the crew being out of hours, they'll park at the next crossing, get into a waiting crew vehicle and be sent back to Sarnia. While I took this D724 with a single unit had gone into the clear at Methes Energies (Sombra customer) and were dropped off to relieve the D725 crew, and would be on the move not long after swapping crews in Sombra.
