Delays on Southern due to signalling problem

There are delays of up to 30 minutes on Southern Trains between Bognor Regis and Horsham, between Bognor Regis and Littlehampton and between Littlehampton and Worthing. It's due to signalling problems at Bognor Regis and Littlehampton.

Southern doesn't currently have an estimate for when normal services will resume.
