Union Station

Signalling system upgrade

Union Station and the adjacent rail corridor are known collectively as the Union Station Rail Corridor (USRC). The USRC is 6.4km long and consists of a complex network of approach tracks, passenger platforms and four control towers at Cherry Street, Scott Street, John Street and Bathurst Street.

We’re upgrading and modernizing the entire signalling system within the USRC – a transformational improvement that will allow us to increase capacity at Union Station and across the GO network.

This work is being completed as part of the Union Station Enhancement Project, which is currently in construction. For more information on project phases, please check out our project lifecycle page.

Project overview

Replacing the signalling system within the USRC is part of Metrolinx's Signalling and Train Control Improvement Program, and an overall revitalization of the USRC that will improve service reliability, help eliminate congestions in the corridor and allow for increase train speeds for future service increases planned with GO Expansion.
