Caption: After getting a tip that this train was slowly moving through Chatham, I raced with anticipation of getting some decent photos of the CN within town limits. Having driven around for about 10 minutes, I finally caught the headlights of 5721 in the distance while crossing Sass Road. I pulled into the (unknown) factory parking lot, and took a position on the now abandoned siding. My goal was to photograph the train coming off of the MacGregor Creek bridge, with the signals showing on either side of the train while it coasted along the eastbound main.. However, without knowing until the train came off the bridge, they took the former westbound main! With CN 5721 leading and 4071 trailing as the second unit, this train quite literally pulled a 'switch' on this photographer! Sometimes you just have to roll with the punches.
