A Southern Railway passenger train derailed near the East Sussex town of Lewes on Thursday afternoon, leaving two people with serious injuries and causing major disruption to rail services across the region. The incident, which occurred at 3:54 p.m., was declared a major incident by British Transport Police, with multiple emergency services mobilizing to the scene.
The 14:24 service from London Victoria to Eastbourne was carrying approximately 150 people when three of its eight carriages left the tracks between Cooksbridge and Lewes railway station and overturned onto their sides. Passengers could be seen standing atop the stricken carriages as emergency responders worked below them, with some travelers having forced their way out of the train into the intense heat.
The scale of the emergency response underscored the severity of the incident. East Sussex Fire and Rescue Service deployed ten fire engines, a command support unit, and technical rescue units to the scene. The South East Coast Ambulance Service sent more than twenty ambulances and three air ambulances. All passengers were eventually evacuated safely from the derailed train.
Medical teams treated twenty people at the scene. Two passengers sustained serious injuries and were conveyed to major trauma centers for further treatment, while eighteen others sustained less serious injuries ranging from cuts and bruises to more moderate harm. The remaining injured and unharmed passengers were initially transported to the Landport Community Hub in Lewes, where paramedics continued to provide medical checks and support agencies distributed water.
The train driver had contacted control at 3:51 p.m., just three minutes before the derailment, to advise of an issue with the train. The cause of the incident remains under investigation, though some reports suggest a track defect may have been responsible. The Rail Accident Investigation Branch deployed a team of inspectors to the site to gather evidence.
The derailment caused immediate and substantial disruption to rail services across East and West Sussex. Network Rail closed all lines through the Lewes area until further notice, with all trains cancelled between Lewes and Brighton, Haywards Heath, Eastbourne, and Seaford. Southern Railway issued a “do not travel” notice for the affected area for the remainder of the day. The railway serves as a major junction, and the closures created a significant bottleneck for regional connectivity, with passengers advised to use alternative bus services or regional rail operators.
Government officials responded swiftly to the incident. Transport Secretary Heidi Alexander said she was “deeply concerned” by the derailment and expressed gratitude to emergency services responding at the scene. She stated that the government was “working quickly with the rail industry and local partners to assist passengers.”
Helena Dollimore, Labour MP for Hastings and Rye in East Sussex, described the news of the derailment as “deeply distressing” and said she had spoken with both the Secretary of State for Transport and the rail minister, who were keeping her updated on the situation. She urged constituents to contact her office if they needed urgent support.
James MacCleary, the Liberal Democrat MP for Lewes, posted on Facebook describing the derailment as “a very serious and developing incident” and said his thoughts were with everyone affected. He urged anyone concerned about someone on the train or needing assistance to contact the emergency services.
The incident occurred on one of Britain’s hottest days of the year, with temperatures reaching 100 degrees Fahrenheit in London, adding to the challenging conditions for both passengers and emergency responders at the scene. Lucy McAuliffe, Network Rail’s route director for Sussex, said the railway between Haywards Heath and Lewes was likely to remain closed for some time as specialist teams carried out complex assessments of the damage to both the train and infrastructure.
