Montreal Transit Chaos: STM Green Line and REM Hit by Back-to-Back Disruptions

For commuters in Montreal, this week has been nothing short of a challenge. The city’s transit arteries, managed by the STM (Société de transport de Montréal) and the REM, experienced a series of frustrating outages that left thousands of passengers scrambling for alternatives during the busiest parts of the day.

Green Line Struggles: A Rough 48 Hours

The Montreal métro’s Green Line has been the epicenter of recent delays. For two consecutive days, the section between Angrignon and Lionel-Groulx stations saw significant service interruptions, causing ripple effects across the city’s transportation network.

• Wednesday’s Breakdown: A train malfunction sparked a shutdown starting before 2:45 p.m. While initial estimates suggested a quick recovery by 3:30 p.m., the outage stretched until after 4:15 p.m., leaving commuters stranded during the early rush hour.
• Tuesday’s Incident: The previous day was equally taxing, with service down for nearly two hours due to a distressing incident involving a person in distress at Jolicoeur station.

REM Network Hits a Snag

As if the métro issues weren’t enough, the Réseau express métropolitain (REM) also reported a sudden interruption on Wednesday afternoon. Around 3:30 p.m., a “rolling stock problem” forced a shutdown of the network section serving both the Deux-Montagnes and Anse-à-l’Orme branches.

The disruption specifically affected travel between Montpellier station and the Des Sources and Île Bigras stations. Fortunately, the REM managed to restore normal service by 4:12 p.m., though the timing coincided perfectly with the STM’s struggles, creating a perfect storm for Montreal travelers.
