Passenger Train Derails Near Lewes in Southern England as Emergency Crews Respond

EAST SUSSEX — Emergency services have mounted a major response after a Southern passenger train derailed near Lewes in southeast England on Thursday afternoon, with at least two carriages photographed lying on their sides.

East Sussex Fire and Rescue Service, paramedics, police and other emergency personnel were deployed near Lewes railway station after the incident. The train was reportedly travelling from London Victoria toward Eastbourne when it derailed.

Early reports did not identify any fatalities, and authorities had not confirmed serious injuries by the latest verified evening information. Some passengers and witnesses reported people suffering cuts and other injuries following the sudden derailment, but official casualty assessments were still being compiled.

Transport Secretary Heidi Alexander said she was deeply concerned by the incident and thanked emergency services responding at the scene.

Images from the scene showed carriages overturned beside the railway, with emergency personnel working around the train. The Rail Accident Investigation Branch was preparing to investigate, while Network Rail and British Transport Police were also involved. All lines through Lewes were closed, causing significant disruption across services in Sussex.

The cause of the derailment had not been established by the evening verification cut-off. That distinction is important because the incident occurred during a period of very high temperatures in southern England. Extreme heat can cause railway tracks to expand and, in some circumstances, buckle, but there was no verified evidence by the evening cycle establishing heat as the cause of Thursday’s derailment.

Investigators will need to examine the track, train, signalling system, maintenance records, speed and other operational factors before reaching conclusions.
