This weekend, August 10-11, the TTC is closing two different portions of Line 1 - one each day - to enable TTC crews to continue installation of the Automatic Train Control (ATC) signalling system.

Replacement shuttle buses will run both days and Wheel-Trans will be available upon request from any station. Customers can speak with a TTC staff member for more information about service frequency.

Saturday

On Saturday only, the portion of Line 1 between Bloor-Yonge and Osgoode stations will be closed until noon. All stations will remain open for fare sales and access to surface routes. TTC staff will be on hand to help direct customers to the appropriate shuttle locations, which will vary from station to station.

Sunday

On Sunday only, the portion of Line 1 between St Clair West and King stations will be closed. All stations aside from Dupont Station will be open throughout the day. TTC staff will be on hand at each affected station to help direct customers to the appropriate shuttle locations, which will vary. As King Station is not yet accessible, customers requiring an accessible connection can use Queen Station instead.

Portions of the TTC's signal system date back to the 1950s when the subway first opened. When ATC is fully installed on Line 1, it will allow improved capacity on the line.  ATC is currently installed on 50% of Line 1, the portion between Vaughan Metropolitan Centre and St Patrick stations. Customers travelling in the ATC area are already experiencing the increased reliability that comes with the modern signal system.
While the TTC does most subway maintenance at the conclusion of service each night, it continues to require weekend and early weeknight closures to complete critical infrastructure and maintenance upgrades.

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.
