The North Sunderland Railway was a four-mile single track branch railway line in Northumberland, England, that ran from Chathill on the East Coast Main Line to Seahouses via the station of North Sunderland with a proposed extension to Bamburgh.
Authorised in 1892 the North Sunderland Railway was built privately to serve the newly constructed harbour at Seahouses. Construction started in 1896, and the line opened in 1898 for freight on 1 August, and passengers on 18 December.
The line was rarely profitable and thus the proposed station at Fleetham, and the extension to Bamburgh were never constructed. Management of the line was taken over by the LNER in 1939.
The line closed on 27 October 1951 and was officially wound up in April 1952.
