Harbourfront streetcar tunnel track work (September 17/18)
During the September 17 weekend, TTC track staff will be working in the Harbourfront streetcar tunnel replacing a section of curved rail and upgrading the existing wheel/rail lubrication unit at the Union Station streetcar loop.
Beginning shortly after midnight (Friday night service) through to Monday morning service, temporary changes will be made to the 509 Harbourfront and 510/317 Spadina streetcar services on the Queens Quay east of Spadina Avenue to accommodate the work in the tunnel.
Although all work will be conducted inside the tunnel, work vehicles and equipment will access the tunnel using the streetcar ramp on the Queens Quay west of York Street. While efforts will be made by the crew to keep noise to a minimum, beeping sounds from back-up alarms on the TTC trucks will be audible.
