Once the stopped train is removed, westbound train service between St-Laurent and Blair is expected to resume this afternoon. Passengers in either direction will need to transfer at St-Laurent. R1 and a St-Laurent–Cyrville shuttle will continue.

Repairs are scheduled to begin around 8 p.m. Tonight, Line 1 will operate between Tunney’s Pasture and Tremblay, with R1 buses between Hurdman and Blair. Repairs are expected to be completed overnight, with regular service resuming Friday morning.
