At about 12:20 p.m. on July 7, 2026, the Réseau express métropolitain halted train service between Panama and Brossard stations in Brossard, Quebec, after an electrical power problem was detected.
The fault forced a temporary suspension of all trains operating on the south‑shore segment of the network, which links Montreal with its southern suburbs. Commuters scheduled to travel between the two stations were advised to seek alternative transportation.
REM officials said the problem originated within the electrical system that supplies the line, prompting an immediate shutdown to ensure safety and to allow engineers to assess and repair the fault. No further details about the cause or expected duration of the outage were released at the time of reporting.
The REM, which began operations in 2023, serves as the primary rapid‑transit corridor for the Greater Montreal area, connecting downtown Montreal with communities on the south shore. Interruptions on the south‑shore line can affect a large number of daily riders who rely on the service for work, school and other travel.
As of the latest update, service remained suspended while maintenance crews worked on restoring power. Riders were directed to consult the REM website and mobile app for real‑time information and to monitor any changes to the service schedule. Passengers were also informed that bus shuttles might be arranged to bridge the gap between the two stations, though details were pending.
The outage underscores the reliance of the network on a stable electrical supply and highlights the importance of rapid response procedures when technical faults arise. The incident is being monitored by the transit authority, which plans to issue a full report once the line is back in operation.
