- Emergency teams activated the ORSEC NOVI mass‑casualty plan and deployed roughly 130–140 firefighters, five medical teams and about 80 vehicles to rescue and care for passengers.
- Officials report 44 people were injured, including an 18‑year‑old woman in critical condition who was airlifted to Rouen University Hospital, while others were treated on site or taken to hospital.
- The public prosecutor and the police judiciaire de Rouen opened a judicial probe; toxicology and drug tests on the driver were negative and investigators say early elements point to a possible collision with an object on the track, though no cause has been confirmed.
