Investigators spot track fault in CCTV before serious UK train derailment
Rail Accident Investigation Branch said CCTV footage showed a track geometry problem right before a passenger train derailed near Lewes, injuring two people.
On Aug 19, the Rail Accident Investigation Branch reported that CCTV images taken moments before a passenger train left the rails near Lewes displayed a track geometry irregularity. The derailment, which happened amid a period of sustained high heat across the country, resulted in serious injuries to two individuals. The agency also observed evidence of earlier track maintenance in the vicinity.
While the railway embankment is built from material sensitive to water content, investigators found no clear proof of a significant slip before the accident, though some prior movement was noted. The inquiry will assess the effectiveness of hot-weather mitigation measures and examine the condition of the train, track and embankment. A comprehensive report will be issued once the investigation concludes.
