The STM says service is gradually resuming on the metro's orange line after a train breakdown suspended service on the busiest line of the metro network for an hour during the evening rush hour. The shutdown began at around 5:30 between Henri-Bourassa and Berri-UQAM stations, though trains were delayed all the way to Cote-Vertu as a result of the shutdown. Service was beginning to slowly resume on the line shortly after 6:30.
