Rouge Hill is a GO Transit train and bus station on the Lakeshore East line. The station is located on the shore of Lake Ontario in West Rouge in the former municipality of Scarborough, the most easterly neighbourhood of Toronto, Ontario, Canada. It is a major commuter transfer point, with large parking lots and local bus services. It is the last station in Toronto before the trains enter Durham Region.HistoryThe earliest Port Union Station was situated at Port Union Road, about half a kilometre west of the current location. The Grand Trunk Railway opened the station in 1856 on its Toronto-Montreal mainline, in what was then the small ship building and fishing village of Port Union.In the days of the steam locomotive, freight trains needed assistance to climb from lake level over the Scarborough Bluffs. Port Union was the easterly end of this helper service with a siding that ran behind the station for waiting locomotives, and a water tower and fuel tanks to resupply westbound trains. With the advent of diesel-electric power those facilities were no longer required and Canadian National Railway subsequently replaced the station with a utilitarian brick building.
