CN Rail announced on Tuesday that trains are once again running on the line that passes through Repentigny, Quebec, following a major derailment that halted traffic on Sunday afternoon. The restored service will operate at reduced speed and will be subject to qualified inspections as the company works to re‑establish normal operations.
The derailment, which occurred north of Montreal on July 5, 2026, forced CN Rail to suspend all traffic through the Repentigny corridor. The incident prompted an immediate shutdown of the route while crews assessed the damage and secured the site. After completing the necessary safety checks, the railway confirmed that the line is now open for traffic, albeit under stricter speed limits and with ongoing inspections to verify the integrity of the track and rolling stock.
CN Rail officials emphasized that the reduced speed and inspection regime are precautionary measures designed to ensure safe passage of trains while any remaining issues are addressed. Qualified inspectors will accompany each train, conducting checks that meet the railway’s safety standards before the locomotives proceed further along the route.
The resumption of service restores a critical link for freight and passenger movements in the region, reconnecting the network that had been disrupted for several days. While the line is operational, the company has not provided a timeline for returning to full speed limits, indicating that the focus remains on maintaining safety while the aftermath of the derailment is fully resolved.
Residents of Repentigny and surrounding communities can now expect trains to pass through the area again, though at a slower pace than before the incident. CN Rail continues to monitor the situation and will adjust operational parameters as additional inspections are completed and the track condition is confirmed to meet standard requirements.
