A Southern Rail passenger train derailed near Lewes in East Sussex, England, on a Thursday afternoon. The train, traveling from London Victoria to Eastbourne with approximately 150 passengers on board, saw at least three carriages derail and overturn on their sides between Haywards Heath and Lewes. British Transport Police declared a major incident, triggering a large-scale emergency response involving fire crews, police, and numerous ambulances. While all passengers were successfully evacuated, the accident resulted in multiple injuries. ~~Updated reports~~ Reports indicate that between 18 and 20 people were treated for injuries, including two individuals who sustained serious injuries and were transported to major trauma centers. Authorities stated that the conditions of those seriously injured were not deemed life-threatening. The Rail Accident Investigation Branch (RAIB) has been deployed to investigate the cause. The derailment has caused significant disruption to rail services and the closure of several lines in the region. While the exact cause remains under investigation, reports suggest that extreme heat may have contributed to the incident, with temperatures reaching 38.1 degrees Celsius, potentially causing track expansion or defects. Transport Secretary Heidi Alexander has expressed “deep concern” regarding the incident.
