Train services between Norwich and London were hit by delays this morning after signalling problems at Liverpool Street.

Services including the 6am and 6.25am services to Norwich were delayed by more than 20 minutes following the problems.

Meanwhile the number of coaches on the 6.40am service to London was reduced from 10 to eight because of an earlier train fault.

National Express East Anglia said the engineers were working to restore services back to normal as quickly as possible.
