Trains to and from Brighton are being disrupted after a signalling fault on a main line station.

The fault, at Preston Park railway station, means trains going through the station have to run at reduced speeds. 

The incident took place at around 3.45pm today but disruption is expected to continue until 6pm. 

A spokesman for Govia Thameslink Railway, the operator in charge of Southern and Thameslink services said: "A fault with the signalling system at Preston Park is causing delays of up to 15 minutes to services running between Haywards Heath and Brighton.

"We anticipate this will continue until 6pm."
