No injuries have been reported; disruption is expected to continue until around midday on the day of reporting.

The incident highlights ongoing challenges in UK rail infrastructure and underscores the push for improved signaling, train management, and passenger communication to prevent future disruption.

A major disruption to south-east England rail services is underway due to a derailment at Selhurst depot and a signalling fault between Norwood Junction and London Blackfriars, affecting Gatwick Express, Southern, and Thameslink operations.

GTR urges passengers to avoid travel if possible and to use alternative routes or modes such as buses or taxis, with real-time updates available on the operator’s website and social channels.

Officials describe the situation as ongoing, with continuous live updates and advisories as more details emerge.

Authorities and rail operators provide multiple channels for live updates and information submission, including live departure boards and partner monitoring.

The article notes broader UK rail nationalisation developments, with GTR anticipated to be nationalised in May and other operators affected by similar moves.
