Caption: Local power for Brockville trailing. CN 373 is passing through Dorval with two GP9's trailing the road power. Those two units (CN 4129 & CN 7083) entered Montreal on CN 586 and are heading back to Brockville. Ahead are CN 2593 & CN 5768. At right is part of an overpass that has been sitting there for about 5 years without it being completed due to the government failing to get permission from CN and CP to build on or over there tracks here before they began work.
