Caption: While sitting just up the Guelph Sub waiting for GEXR 582 to return to The York Road yard, from behind me I see train headlights coming towards me. It was GEXR 583 with STL&A 3804 and its slug mate STL&A 804. Out I jumped and they pulled up right in front of me and the conductor dismounted and threw the switch to head down the spur. I've never saw a train head that direction so off I went to a few locations to shoot it . I figured it was going to Owens Corning and was right. They retrieved the two cars and headed back across York Road. The wind and flags cooperated nicely. Thanks to Jacob in aiding in the editing.
