SNCF Line N Interrupted Between Paris and Versailles, Chaville Station Closed for Security Reasons
Paris, March 2, 2026 – Traffic on Transilien Line N was interrupted between Paris-Montparnasse and Versailles-Chantiers on Monday, March 2, 2026, due to security measures issued by the police. Chaville station in Hauts-de-Seine was also evacuated and closed for several hours. The disruption, which began around 4 PM, affected commuters traveling between the capital and the Yvelines region.
Security Threat Prompts Service Suspension
The SNCF announced the interruption via its social media channels, stating that the decision was made due to “security measures issued by the police forces.” According to information provided by the SNCF to Actu Paris, the police prefecture requested the suspension of services around 4 PM due to a potential security threat to passengers. Sources suggest the threat might have originated from a building near Chaville station.
The closure of Chaville station and the interruption of Line N services caused significant disruption for thousands of daily commuters. Bus lines 6131, 6132, 6133, and 6134 were also affected, further complicating travel in the area.
Service Resumption and Ongoing Investigation
While traffic on Line N between Paris and the Yvelines was largely restored before 6 PM, Chaville station remained inaccessible until just before 7 PM. The SNCF confirmed the reopening of Chaville station and the full resumption of Line N services shortly after 7 PM.
As of the latest update, the Paris Police Prefecture had not yet provided further details regarding the nature of the security threat. An investigation is likely underway to determine the exact circumstances that led to the disruption.
Impact on Commuters and Public Transport
The incident highlighted the vulnerability of public transport networks to security concerns and the immediate impact such events have on urban mobility. Commuters faced delays and had to seek alternative routes, underscoring the importance of swift and effective responses from transport authorities and law enforcement.
This event follows a previous incident where a deputy from Côtes-d’Armor was accused of assaulting an SNCF agent at Montparnasse, indicating a broader context of security challenges within the French rail system.
The SNCF and local authorities continue to monitor the situation and ensure the safety of passengers across the Transilien network.
