Heads-up Millennium Line passengers! As part of our regular maintenance program, crews will be grinding rails this Friday, July 14 and Saturday, July 15, resulting in modified late evening service.

From 11 p.m. until the end of service, a shuttle train will operate on the Millennium Line between Renfrew, Commercial–Broadway and VCC–Clark stations in both directions. Passengers travelling through Renfrew Station, please allow 5-10 minutes extra travel time to switch between the trains.

Expo Line trains—Waterfront to King George Station and Waterfront to Production Way–University Station—will operate normally. Canada Line is unaffected by this work.

What is rail grinding?

Rail grinding is standard maintenance work that we do on a regular basis on the Expo and Millennium lines, to improve ride quality, reduce noise levels, and extend the rail’s life. A locomotive pulls two trailers that have grinding stones, removing a small amount of steel from the rail to remove surface imperfections and re-profile the rail to improve ride quality.

A short-term side effect of this work is increased noise from anywhere between a few days to a couple of weeks while the freshly ground rail adjusts to the train’s wheels. We thank our neighbours and customers for their understanding while we complete this important maintenance work.
