Caption: TH&B GP7 77 and GP9 402 sit near the PC-TH&B yard office/station building at Welland Yard, a few tracks over from the PC Canada Division mainline on the left. (the old Canada Southern/CASO line through southern Ontario). This appears to be an evening shot, perhaps power for a TH&B job waiting to lift its train and head back to Hamilton (one of the resident TH&B experts may have more insight).
