A FAULT on a railway line is causing cancellations and delayas to train services.
The fault with the signalling system at Horsham means that "all lines are disrupted".
Southern Rail warned passengers to expect trains running through this station to "be cancelled or delayed by up to 30 minutes".
Disruption is expected to continue until 2pm.
A spokesman for the transport company said: "A track circuit failure at Horsham station has disrupted services running through the area.
"Network Rail is working to fix the issue as quickly and safely as possible.
"Services through Horsham will be delayed by up to 20 minutes or may be cancelled at short notice.
"Horsham to Peterborough services will be terminating/starting at Three Bridges where possible.
"Please check your journey before you travel and listen to announcements at the station."
