Accident at Coignières Intersection Halts Rail Services
According to the X (formerly Twitter) account of Rémi Train Paris Chartres, a road accident occurred at an intersection near a rail bridge in the commune of Coignières (Yvelines) this Wednesday morning, March 4, 2026. This incident led to the immediate suspension of train traffic in both directions on the Paris Montparnasse – Rambouillet line.
SNCF teams were promptly dispatched to the scene to assess the damage and undertake necessary repairs. “Our teams are on site to carry out the necessary repairs,” stated the transport network, acknowledging the inconvenience caused to passengers.
Impact on Commuters and Service Resumption
Travelers faced considerable delays and disruptions. The initial announcement for service resumption was set for 11:15 AM, but traffic was effectively restored at 12:10 PM. However, the 11:05 AM train from Paris Montparnasse to Le Mans was partially canceled and had to depart from Rambouillet, with a delay exceeding 30 minutes.
The incident also affected Line N services between Rambouillet and La Verrière, which experienced a complete halt before a gradual and then full resumption of traffic around 12:20 PM. Commuters were advised to check real-time updates for their specific routes.
Ongoing Efforts for Rail Safety and Efficiency
This incident highlights the vulnerability of rail services to external factors such as road accidents. Authorities are continuously working to enhance safety measures and improve response times to minimize disruptions for passengers.
The affected lines are crucial for daily commutes in the Île-de-France region, connecting Paris with several suburban areas. The prompt action by SNCF teams ensured that the interruption was as brief as possible, mitigating further impact on thousands of daily travelers.
Further investigations into the exact circumstances of the road accident are expected to be conducted by local authorities to prevent similar occurrences in the future.
