This weekend, Feb. 3-4, TTC crews will continue installation of the Automatic Train Control (ATC) signal system. In order to complete this work, the portion of Line 1 Yonge-University between St Clair West and Union stations will be closed.

Throughout the closure, express shuttle buses will run between Spadina and St Clair West stations only. The TTC encourages customers to use the following alternatives:
- Line 2 Bloor-Danforth
- Yonge portion of Line 1
- 6 Bay bus
- East-west streetcars on College, Dundas, Queen and King Sts. to connect with the Yonge portion of Line 1

St Clair West, Spadina, St George and Union stations will be open for fare sales and connections to surface vehicles. All other stations on this part of Line 1 will be closed.

When ATC is fully implemented in 2020, it will provide a more modern and reliable signal system that will allow for an increase in the number of trains operating on Line 1.

While the TTC does most subway maintenance at the conclusion of service each night, it continues to require weekend closures to complete ATC and state-of-good-repair work. One weekend of work during a closure is equivalent to about five weeks of nightly work.

This is the first of three such closures on this portion of Line 1 in 2018. This year, there will be a total of 39 full weekend closures, three one-day closures and seven late openings. Metrolinx requires 24 closures to accommodate Eglinton Crosstown LRT construction at Yonge St. and Eglinton Ave. The TTC will take advantage of those closures for maintenance and upgrades in the affected areas.

The next scheduled subway closures are:
- Feb. 10-11 - Line 1 Yonge-University: St Clair to Lawrence for Metrolinx construction on the Eglinton Crosstown LRT
- Feb. 17-18 - Line 1 Yonge-University: St Clair to Lawrence for Metrolinx construction on the Eglinton Crosstown LRT
- Feb. 24-25 - Line 1 Yonge-University: St Clair to Sheppard for Metrolinx construction on the Eglinton Crosstown LRT and TTC track work.
