Two passenger trains derailed within 24 hours in southern England, disrupting services and prompting safety investigations. The first incident occurred near Lewes, East Sussex, on 13 August 2026, when a Southern train from London Victoria to Eastbourne left the tracks. Three carriages overturned, injuring two passengers seriously and 18 others with less severe injuries.
The following day, a Greater Anglia service derailed near Wickford station in Essex. Two carriages came off the tracks but remained upright. No injuries were reported, though emergency services attended the scene. National Rail confirmed that no trains would run between Wickford and Southend Victoria until at least the end of 14 August 2026.

Investigations and safety assurances
The Rail Accident Investigation Branch (RAIB) is leading inquiries into both incidents. The Department for Transport confirmed investigators were deployed to the Wickford site. A spokesperson said the UK’s railways remain among the safest globally but added that such incidents are taken seriously.
Martin Frobisher, Network Rail’s group safety and engineering director, acknowledged public concern but reassured passengers. He said, "Britain’s railways still rank among the safest in the world, and safety is always our first consideration." Frobisher also noted that extreme summer weather had created exceptional challenges for track conditions.
