CN Rail has resumed train movements through Repentigny, Quebec, after a major derailment forced a temporary halt. Trains are now running at reduced speed while qualified inspections are under way to verify track safety.
The derailment occurred north of Montreal on Sunday, July 5, 2026, and caused an immediate suspension of CN Rail traffic in the area. In response, the railway imposed a temporary speed restriction on the affected corridor to protect workers and the public.
Qualified personnel are conducting detailed inspections of the track, ties, and surrounding infrastructure. The purpose of the inspections is to confirm that the line meets safety standards before normal operating speeds can be restored.
The reduced‑speed operation will remain in effect until the inspections are completed and any necessary repairs are carried out. No additional information about the cause of the derailment has been released at this time.
The incident underscores the importance of rapid safety responses for freight rail operators in the region. Residents and businesses along the route have been advised that service will continue at a slower pace while work proceeds.
CN Rail has not provided a specific timetable for returning to full speed, but it has emphasized that safety remains the top priority as it works to restore regular service through Repentigny.
