Preliminary findings from the Rail Accident Investigation Branch (RAIB) have revealed a track irregularity at the location of a recent derailment close to Lewes.

The defect, described as an 'anomaly' in the rail surface, was detected during the initial phase of the inquiry into the incident, which occurred on [date if known, otherwise: earlier this week]. The RAIB's report, published on Thursday, suggests the issue may have contributed to the train leaving the tracks, though further analysis is required.

A team of investigators has been examining the site, along with maintenance records and operational data, to determine how the irregularity developed and whether it had been flagged prior to the incident. The stretch of line has remained closed since the event, with engineers undertaking a full inspection.

Network Rail has stated that it is cooperating

Network Rail has stated that it is cooperating fully with the investigation and has initiated its own review of the affected infrastructure. Passengers have been advised to expect continued disruption, with replacement transport arranged.

The RAIB has stressed that the findings are interim and that no definitive conclusions will be drawn until all evidence is assessed. A full report is expected in the coming months.
