Lewes derailment exposes Sussex rail network's single-point vulnerability

A Southern train derailed near Lewes station on 13 August 2026, blocking all lines and cutting routes between Ore, Eastbourne, Seaford, and Brighton. Lewes is the sole junction linking the Eastbourne and Seaford branch lines with the main Brighton-to-Hastings route — so one failure there severs multiple corridors with no alternative pathway. No restoration timeline has been given.
