New Union Station Signalling System Means Improved Service for Transit Riders

Ontario Improving Public Transit, Creating Jobs

Ministry of Transportation

Ontario is making it easier for commuters to take public transit and is relieving congestion in the Greater Toronto Area and Hamilton Area (GTHA) with improvements to the entire signalling system within the Union Station Rail Corridor.

Replacing the Union Station Rail Corridor signalling system is part of Metrolinx's signalling and train control improvement program, and the next phase of a revitalization that will improve service reliability, eliminate track bottlenecks, increase train speeds and reduce operating costs.

Upgrades to the 80-year-old signalling system will ensure GO Transit can prepare for the anticipated doubling of ridership over the next 10-20 years.

Building smarter, more integrated transit is part of the government's economic plan for Ontario. The four part plan is building Ontario up by investing in people's talents and skills, building new public infrastructure like roads and transit, creating a dynamic, supportive environment where business thrives, and building a secure savings plan so everyone can afford to retire. 

Quick Facts

  • Work to upgrade and install the new signalling system will begin in 2015 and is expected to be completed by 2019.
  • The project is valued at $365.5 million. Ontario and Metrolinx are contributing $273.5 million to the project with the Government of Canada contributing up to $92 million through the Canada Strategic Infrastructure Fund.
  • The Union Station Rail Corridor, running from the Don River in the east to Strachan Avenue in the west, is about 6.4 km long and contains 40 km of track, with as many as 16 tracks lined up alongside one another in the busiest part of the corridor.
  • The corridor contains 228 signals that train engineers must follow, as well as 221 track switches that allow trains to change tracks at they move through the corridor.
  • Three major contracts have been awarded to deliver this project: Signalling (awarded to Alstom Transport), Technical Consultant Services (awarded to Hatch Mott McDonald) and Electrical Enabling Works (awarded to Plan Group).
  • On a typical weekday, approximately 200,000 GO Transit passengers travel to and from Union Station. GO Transit carries approximately 66-million passengers per year.
