An ongoing investigation into a train derailment near Lewes has identified a defect on the track, according to initial findings from the Rail Accident Investigation Branch (RAIB). The RAIB is examining the circumstances surrounding the incident, which occurred on a curved section of track.
The investigation will consider various factors, including how the specific section of track was inspected and maintained, the condition and upkeep of the embankment, and the impact of weather conditions, as well as the effectiveness of any hot weather mitigation measures that were in place.
In a joint statement, Lucy McAuliffe, Network Rail's route director for Sussex, and John Whitehurst, chief executive of Greater Thameslink Railway, offered apologies for the derailment. They stated, "We will carefully consider any recommendations arising from the investigation and work across the industry to implement them, with the shared goal of making an already safe railway even safer for our customers, colleagues and the communities we serve."
The derailment involved a passenger train that had departed from London Victoria and was en route to Eastbourne. The incident resulted in three carriages leaving the tracks and tilting beside the railway line. Emergency services attended the scene, and rail workers were present to assess the damage and assist with the investigation.
