As part of its program to maintain streetcar tracks in a state of good repair, TTC crews are grinding the rails on a number of sections of the streetcar network that have developed roughness. This work improves the condition and extends the life of the rail and provides a smoother streetcar operation through those areas.
From 9 p.m. Wednesday, March 18 until 5 a.m. Thursday, March 19, crews are grinding the rails
- on St. Clair Avenue West between Old Weston Road and Silverthorn Avenue / Hounslow Heath Road.
The TTC is detouring streetcars along this route, while the crews are working:
- 512 St Clair.
Shuttle buses replace the cars west of Lansdowne Avenue.

Crews start operating the slow-moving rail-grinding unit about 9 p.m. and continue overnight until about 5 a.m. They use a street sweeper to clean the track area every day after grinding the rail. You may hear noise when the rail-grinder and street-sweeper are operating.
While crews only work on the streetcar tracks, the City of Toronto will restrict on-street parking through the work zone to maintain traffic flow.
Toronto Police Services officers will be on-site each night to help direct traffic at the intersections in the work zone.
