Train passengers travelling to Sheringham and Cromer from Norwich today will have to use a replacement bus service.
The disruption has been caused by the planned work by Norfolk County Council to build a bridge over the railway at Rackheath for the Norwich Northern Distributor road.
Rail replacement buses are also in action between Norwich, Diss and London Liverpool Street today because of engineering work at Shenfield.
More than 250 buses are running.
