Caption: GO 507 is temporarily on CN passenger service as train #73 races westward alongside a freight about to head up the Dundas sub. The passenger is pulling 9 coaches; the freight, behind CN 9631, 4584, 4536 and 9647 according to my notes are 87 cars and caboose 79568 in tow. Nobody out on the walkbridge this day; and interesting to note how wide open the "railfan house" is back then. We used to comment on being the owner of that house if it ever came up for sale.
