Caption: VIA FP9 6521 leads two 6600-series F9B units on an eastbound "Corridor Canadian" consist, passing CN workers doing some track upgrading on the Kingston Sub around Mile 301, as viewed from Park Road South overpass. The east end of CN's Oshawa Yard is visible, serving GM's large Oshawa assembly plant in the upper left background.

If you look very closely, you can see the domes of the Skyline and Park cars. In the early-mid 1980's, The Canadian's consist between Toronto-Montreal was run mixed with corridor trains (e.g eastbound #2 combined with #44/54) in order to, according to Eric Gagnon's post on the subject, cover the Toronto-Montreal stretch (as Sudbury-Montreal had been cancelled) and service the passenger equipment at The Glen yard in Montreal.
