Starting from Friday, October 9, 2026, and continuing at least through Saturday, October 10, the SNCF Info Traffic application will need to be monitored closely due to ongoing disruptions in train services. The disruptions follow a strike by train controllers, which was triggered by a knife attack on an employee on the Paris-Rouen line on Friday, October 2, 2026. Bastien Sellier, general secretary of the CGT railway workers in Rouen, said, "For years, we have been demanding more resources, but the company does nothing. This knife attack is the final straw. We are not here to take knife blows for the company." On the morning of October 2, a 13-year-old boy attacked a controller on the Paris-Rouen line, attempting to stab the agent multiple times before being arrested. This incident has heightened tensions on the Normandy rail network. Baptiste Bauza, a CGT railway militant in Le Havre, noted, "A general feeling of insecurity. Since the derailment in Cléon and the discovery of a broken rail on the Caen-Rennes line, we are in a very tense context. This attack reinforces the general feeling of insecurity." The four unions involved—CGT railway, Sud rail, UNSA, and CFDT railway—are demanding more human resources. Bastien Sellier emphasized, "We want there to be two controllers per train and per element, for the safety of the controllers and passengers." Another key demand is the screening of the last trains departing from Normandy and Paris by railway safety authorities. Train traffic will remain normal on most lines of the Nomad network, but disruptions are expected on specific routes. These include the NOMAD RÉSA lines: Paris to Rouen to Le Havre, Paris to Caen to Cherbourg, and Paris to Lisieux to Trouville/Deauville. The NOMAD lines affected are Paris to Vernon to Rouen and Paris to Évreux to Serquigny. Specific measures have been put in place to allow free exchanges or refunds of tickets: https://t.co/wNfv9SPuIl. Impacts are expected on Saturday, October 10, and details will be available online during the day. Passengers are advised to check train traffic the day before starting at 5 p.m. Disruptions are also expected on Friday, September 9, and Saturday, October 10, 2026, on the listed routes.
