The 9.45am Greater Anglia service from Norwich to Sheringham has been cancelled due to a fault with the signalling system. The 10.47am from Sheringham to Norwich has also been cancelled.

On Twitter Greater Anglia tweeted: 'Due to a fault with the signalling system between #Norwich and Hoveton & Wroxham some lines are blocked. Services running to and from these stations may be cancelled, delayed or revised.'

The disruption is expected until 11:00
