Caption: In its last months of operation, CP train No. 21 makes its station stop at Guelph Junction behind a pair of steam-generator equipped RS10s units. Come April 26 (1964), the conventional train will be replaced by RDCs west of Toronto (it continued as an overnight train between Montreal and Toronto for a couple more years). Westbound No. 21 departed Toronto at 8:30 AM and had a flag stop at Guelph Jct at 9:37; it's eastbound counterpart No. 22 was still a named train in the timetable, "the Overseas", departing Detroit at 4:25 PM, Guelph Jct at 9:05 PM and arriving Toronto at 10:20 PM.
