A service interruption on Montreal's Réseau express métropolitain (REM) affected the segment between Gare Centrale and Panama stations on the afternoon of June 16, 2026. Emergency services intervened on the line, prompting REM operators to halt trains traveling between the downtown hub and the Panama stop.

The disruption began in the early afternoon, and REM announced that all trains on the affected stretch would remain stopped until the situation was resolved. Emergency personnel were dispatched to the site, and their presence required the rail corridor to be cleared for safety reasons. The exact nature of the emergency was not disclosed, but the intervention was sufficient to suspend operations for several hours.

Commuters traveling on the line were advised to seek alternative transportation. Nearby bus routes and other transit options were suggested for riders needing to reach destinations along the central corridor. REM indicated that stations outside the affected zone continued to operate normally, and that information would be updated as the situation developed.

The REM network, a key component of Montreal's public transit system, links the downtown core with surrounding neighborhoods and suburbs, providing rapid, electric rail service across the city. The line between Gare Centrale and Panama is a heavily used segment, connecting downtown commuters with residential areas to the west.

Authorities expected to resume service once emergency crews completed their work and the tracks were deemed safe. REM officials said they would monitor the situation closely and provide updates through their communication channels. The incident underscores the importance of rapid response coordination between transit operators and emergency services to maintain safety and minimize disruption for the city's riders.
