Rail passengers heading in and out of Norwich on the London mainline are facing major disruption this afternoon because of a signalling problem at Ipswich.

Train operator National Express East Anglia said that because of the problems there were hour long delays on all trains travelling through Ipswich.

All trains between Ipswich and Felixstowe are also currently suspended.

The firm said the delays were likely to be in force until around 6pm.
