The Northumberland Line is a planned railway project aimed at reintroducing passenger rail services to freight-only lines in South East Northumberland, North East England. Under the scheme, a new passenger service would link some of Northumberland's major population centres in Ashington and Blyth to the nearby city of Newcastle upon Tyne. Construction of new stations and works to upgrade the existing rail infrastructure to bring it up to passenger-carrying standards is reported as having begun by late August 2022, ahead of the anticipated launch of the new passenger service in December 2023.
