Grease, Not Morning Dew, Caused REM Train Delays in Montreal
On Wednesday, June 3, 2026, commuters on Montreal's REM line faced significant delays due to grease on the tracks, contrary to initial social media speculation that morning dew was to blame. The incident disrupted the morning commute, causing frustration among passengers.
According to officials, the grease accumulation on the rails led to reduced traction, forcing trains to operate at slower speeds for safety reasons. The exact source of the grease is under investigation, but it is believed to have originated from nearby construction or maintenance activities.
Social media posts had earlier suggested that the delays were caused by morning dew, but REM authorities quickly clarified that grease was the actual culprit. The misunderstanding highlights the rapid spread of misinformation during transit disruptions.
REM, the Réseau express métropolitain, is a light rail network serving the Greater Montreal area. This is not the first time the system has faced operational issues, but officials assured that measures are being taken to prevent future occurrences.
Passengers were advised to allow extra travel time and to check for updates on the REM website and social media channels. The delays were resolved by mid-morning, and normal service resumed.
