CN Rail announced Sunday that train traffic on its main line north of Montreal has resumed following a major derailment that occurred on July 5. Service is now operating, but trains are limited to reduced speeds and will undergo qualified inspections before proceeding.
The incident unfolded on Sunday afternoon in Repentigny, a community located just north of the city of Montreal in the province of Quebec. The derailment involved CN Rail equipment and prompted an immediate shutdown of the affected track segment while authorities assessed the situation.
In accordance with safety protocols, CN Rail has instituted a series of qualified inspections on the damaged section before allowing trains to move at normal speed. Until those checks are completed, locomotives will travel at a slower pace to ensure track integrity and passenger safety.
The reduced‑speed operation is expected to affect scheduled departure and arrival times on the corridor that connects Montreal with points eastward. Freight and passenger services will continue, but crews have been instructed to monitor track conditions closely and report any irregularities.
The derailment on July 5 was described by CN Rail as a significant event that triggered the company's emergency response plan. Standard procedures call for a thorough examination of rolling stock, track infrastructure, and signaling equipment before normal service can be restored.
CN Rail officials indicated that inspections will continue throughout the week and that the line will be cleared for full speed operation once all safety criteria are met. Travelers are advised to check updated schedules as the company works to return the corridor to regular service levels.
