Caption: With a short train of cars from customers along the Uxbridge Sub and "Golden Mile" area to the east, CN 7028 and 7083 lead local #543 through downtown Toronto, past towering condos and the sprawling trackage of Union Station, back to Mimico Yard. Note the Air Canada Centre, which was formerly a postal handling facility attached to Union Station via underground corridors. The platforms stretching outside of Union Station are for the most part long disused as GO and VIA almost always load their trains under the train shed. In the upper right, part of the ex-CPR John Street Roundhouse and coaling tower can be seen, now a railway museum.
