This weekend, Feb. 23-24, 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.
Shuttle buses will run, stopping outside each station along the route. Dupont and Museum stations will be closed over the weekend, but all others will remain open for fare sales and access to surface routes.
There will also 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.
Wheel-Trans will be available upon request from any station throughout the weekend. Customers can speak with a TTC staff member for more information about service frequency.
When ATC is fully installed on Line 1, it will provide a more modern and reliable signal system that will help the TTC improve capacity by allowing for increased trips on the line. While the TTC does most subway maintenance at the conclusion of service each night, it continues to require weekend closures to complete critical infrastructure and ATC upgrades, as well as work on the Eglinton Crosstown.
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.
The next scheduled subway closures are:
Mar. 4-7 at 11 p.m. nightly - Line 1: St Clair West to Union stations for ATC signal upgrades
Mar. 11-14 at 11 p.m. nightly - Line 1: Finch to Lawrence stations for track maintenance and repair
