A Portion of TTC Line 1 to close for ATC signal upgrades and track maintenance

This weekend, Mar. 30-31, the portion of Line 1 between St Clair West and Union stations will be closed as TTC crews continue installation of the Automated Train Control (ATC) signal system.

The same portion of Line 1 will also close early nightly next Mon., Apr. 1 through Thurs., Apr. 4 for track maintenance.

Shuttle buses will run during both sets of closures, stopping outside each station along the route. Dupont and Museum stations will be closed, but all others will remain open for fare sales and access to surface routes.

Wheel-Trans will be available upon request from any station. Customers can speak with a TTC staff member for more information about service frequency.

Over the weekend, there will be extra service on the 510 Spadina and 512 St Clair routes to provide customers with other travel options to get to and from Union Station. Customers can use the 510 to travel between Spadina and Union stations or the 512 to get to the Yonge side of Line 1.

The TTC is committed to keeping customers informed about work and events that impact service and about alternative routes. For the most up-to-date information, follow @TTCNotices on Twitter or sign up for eAlerts.
