Alstom working to resolve issues affecting REM
Posted January 30, 2026 4:57 pm.
The company responsible for Montreal’s Réseau express métropolitain (REM) trains has promised to implement solutions after acknowledging that its trains have been unreliable since the opening of a new branch line last November.
Alstom Canada says it has identified faulty electronic components as the cause of many recent disruptions affecting the network.
In a press release, the company said it expects to complete repairs in the coming days.
It admits that service has fallen short of expectations, with frequent delays, particularly on the 30-kilometer extension of the REM, which opened on November 17 and connects Central Station in northwest Montreal via Laval to Deux-Montagnes.
Quebec Transport Minister Jonatan Julien said the situation is unacceptable and that he has had numerous discussions with CDPQ Infra, the network owner, Pulsar, the operator, and Alstom.
“I expect an improvement in service reliability for users,” he added on social media.
