French train derails at 140 km/h in Normandy injuring 44 as police probe sabotage

Collision and derailment in Seine-Maritime

A regional TER passenger train travelling at 140 kilometres per hour derailed on Friday evening, 11 September 2026, in Normandy. The train was carrying between 180 and 186 passengers along the line connecting Rouen and Caen when it struck an obstruction at approximately 19:45. The collision occurred in the commune of Cléon, located in the Seine-Maritime department, between the stations of Tourville and Elbeuf-Saint-Aubin. The impact tore away the bogie of one carriage, forcing the train off the tracks and sending stones from the track bed flying into the passenger compartments.

Louis, a 24-year-old passenger on board the derailed service, described the moments of the impact to the regional broadcaster Ici Normandie.

All of a sudden there were jolts and, after three seconds, the intensity increased more and more. I could no longer stay seated in my place... The windows partially blew out and ballast stones entered the carriage.

Emergency response and casualties

The derailment injured 44 people on board the train. While 43 passengers sustained lighter injuries and received immediate medical evaluation on site, an 18-year-old woman suffered critical trauma and was transported by helicopter to a regional hospital in life-threatening condition. Normandy Regional Prefect Jean-Benoît Albertini travelled directly to the crash site to supervise the emergency operation and coordinate local administrative efforts.

First responders deployed extensive resources to secure the perimeter and assist passengers stranded in the carriages. The mobilization included 130 firefighters, 80 emergency vehicles, and five specialized medical teams dispatched across the rural crash site. Caen Mayor Aristide Olivier commended the emergency workers on social media and expressed municipal solidarity with the victims and their families following the crash.

Sabotage investigation and judicial inquiry

French police and judicial authorities immediately focused their investigation on the hypothesis of deliberate sabotage. Forensic investigators discovered a severed section of steel rail placed intentionally across the tracks to obstruct the approaching train. Images showing the cut metallic segment positioned across the ballast circulated widely on social media platforms shortly after the derailment.

The public prosecutor in Rouen, Sébastien Gallois, initiated a formal judicial inquiry for deliberate endangerment, assigning the investigation to the regional judicial police. Gallois confirmed that mandatory toxicological and breathalyzer examinations administered to the train driver returned negative results. During a press conference detailing the procedural steps, Vice-Prosecutor Marie-Valérie Albert addressed the anticipated timeline of the inquiry.

The investigation will be long.

Network disruptions and infrastructure repair

The derailment caused severe disruptions across the regional rail network connecting Normandy with surrounding departments. National rail operator SNCF organized replacement bus services to transport stranded passengers between Rouen and Caen while pledging complete transparency and cooperation with the judicial authorities.

Technical inspection teams arrived at the site late Friday evening following the evacuation of all passengers to assess structural damage to the rails and evaluate the heavy lifting machinery needed to right the derailed carriages. Engineering crews resumed technical evaluations on Saturday morning, 12 September 2026, working toward a late-morning assessment of the timeline required to complete track repairs and restore service.
