Lewes derailment reveals Sussex rail's single-point vulnerability

A Southern train derailed near Lewes 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 branches to the main Brighton–Hastings route — one failure there severs multiple corridors with no redundant pathway. No restoration timeline has been given.
