Description

A number of incidents today are affecting services on the Southern network. Services running on the network may be delayed, cancelled or revised.

Disruption is expected until 17:30.

Customer advice:

Southern services have been affected by a number of disruptive incidents today.

As a result, Southern services on our West Coastway and Mainline routes are subject to delays, cancellations, and alterations.

You should check station screens, listen to announcements, and use journey planners before you travel.

You will need to leave at least 30 minutes additional time to complete your journey. You may need to travel on a different train to normal, or change trains at an intermediate station to complete your journey.

Service alterations

Services which usually run between London Victoria and Portsmouth Harbour / Bognor Regis via Horsham will resume running along their booked route, in the London-bound direction. Running towards the south coast, these services are expected to continue running via Hove instead of Horsham.

Additionally, some services which usually run on the 'fast' lines between Purley and Gatwick Airport may instead run on the 'slow lines' via Redhill, taking longer than usual to complete their journey.

The incidents affecting service as follows:

  • A safety inspection of the track earlier today between Gatwick Airport and Purley

  • A fire next to the track earlier today at East Croydon

  • A tree on the railway earlier today between Horsham and Three Bridges

  • A tree on the railway between Horsham and Amberley

  • An obstruction on the track earlier today between Portsmouth & Southsea and Bedhampton

Your ticket will be accepted on the below at no additional cost:

  • Great Western Railway services between Guildford, Redhill, and Gatwick Airport

  • Southern services between London, Brighton, Portsmouth Harbour, and Southampton Central

  • South Western Railway services between London Waterloo, Portsmouth Harbour and Southampton Central

  • Thameslink services between London and Brighton

  • London Underground between London Terminals

  • Stagecoach Buses between Brighton and Durrington-on-Sea, and between Chichester and Portsmouth

  • Metrobus 200 between Horsham and Gatwick Airport
