The TTC’s first closure of 2019 will be this weekend.
On January 12 and 13, a portion of Line 1 will be closed between St Clair West and Union stations as TTC crews continue installation of the Automated Train Control (ACT) signal system.
Shuttle buses will run throughout the closure. Dupont and Museum stations will be closed over the weekend, but all others will remain open for fare sales and access to surface routes.

The TTC says that when the 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 work on infrastructure, ATC upgrades, and the Eglinton Crosstown.
