Caption: CN C40-8M "Saggin' Wagon" 2408 and newer ES44DC 2265 switch the north end of the Brampton Intermodal Terminal on #149, likely having just arrived inbound on its Halifax-Montreal-Chicago journey westbound. I believe standard operating procedure after yarding their train was to send #149's power light from BIT to MacMillan Yard, and new freshly shopped power would head over to BIT later for #149's departure after BIT was done shuffling off/on containers.

Aside from the Highway 7 / Queen Street overpass, there's not that many accessible spots to get shots of BIT yard, and droning is probably out of the question due to it's proximity to Pearson Airport. Shooting from Tracy St. nearby works in a pinch (but can be greatly improved with snowfall as the city plows tended to pile up the snowbanks here).
