One person has died and two others are injured following a collision with a REM train on Montreal's South Shore. The incident occurred early Saturday morning near the Du Quartier station, prompting an emergency response that suspended train service in the area.

Longueuil police received a call about the incident around 3:10 a.m., a time when no scheduled trains were operating. Authorities confirmed that three young men were struck by the train. A 19-year-old was pronounced dead at the scene, while a 22-year-old is in critical condition with serious injuries. Another 19-year-old has since been reported as out of danger.

The REM communications department stated that the collision happened due to "an intrusion onto the tracks." According to Sûreté du Québec spokesperson Sgt. Ève Brochu-Joubert, a group of individuals attempted to cross Highway 10 and the REM tracks despite the approaching train. "They continued walking," she said.

In response to the incident, train service has been suspended between the Du Quartier and Brossard stations in both directions. A shuttle service has been established to accommodate passengers during the disruption. Provincial police are currently investigating the circumstances surrounding the collision.

The situation has raised concerns about safety on the tracks, especially during times when no trains are scheduled to run. Authorities are urging the public to exercise caution around railway crossings and to adhere to safety protocols.

As investigations continue, the REM has not provided a timeline for when normal service will resume.

This tragic event highlights the importance of railway safety and the potential dangers of trespassing on train tracks.
