There is further disruption for rail passengers across rural routes because of ongoing signalling problems, including services between Norwich and Sheringham via Cromer.
Greater Anglia says Norwich to Sheringham services are running at reduced speed, causing severe delays.
As a result train services from Norwich will terminate and start from Cromer.
A rail replacement bus service has been running between Cromer and Sheringham from 6am until 8pm.
Greater Anglia and Network Rail have apologised if travel has been affected by the problems.
