REM Service Faces Major Disruption

Service on Montreal's Réseau express métropolitain (REM) was significantly slowed during the Thursday morning commute on November 27, 2025. The automated light-rail system experienced a technical problem, causing delays and frustration for passengers across the network.

Official Communication and Uncertainty

The disruption was officially confirmed by REM authorities through a post on the social media platform X, formerly known as Twitter. In their announcement, they cited a "technical problem" as the cause of the service slowdown affecting both directions of travel. Crucially, the transit operator did not provide any estimated timeline for when regular service would be restored, leaving commuters in a state of uncertainty.

Impact on Montreal Commuters

The timing of the issue, occurring during the busy morning rush hour, meant it had a substantial impact on a large number of people. With no immediate resolution in sight, passengers were forced to seek alternative transportation or face extended wait times. This incident highlights the growing reliance on the REM system for daily travel in the Montreal region and the widespread effects when such a critical piece of infrastructure encounters operational difficulties.

The story was developing throughout the morning, and the REM's communications team was expected to provide further updates as they worked to resolve the technical fault and restore full service to the network.
