Caption: CN L518 backs up towards Invista, as they cross a little wooden trestle going across the Little Cataraqui Creek, in Kingston ON. Up front is GMTX 2254, & a surprise visitor (GTW 6224). Apparently the heater on the GTW wasn’t working, so the whole time the GMTX had to lead per crew preference, so when the GMTX came in leading eastward, heading westward they wyed the train at the Kimco Wye at Queens.
