English Heritage is urging the public to give their views on historic structures along the railway line between Sheffield and London.
The organisation has started a three-week consultation on the heritage of the Midland Main Line railway before the route is the electrified.
Bridges, viaducts and tunnels along the route – including Sheffield’s Bradway Tunnel and a stone viaduct south of Dronfield are among structures which will be considered for listed status.
Much of the line is one of Britain’s oldest railways, dating back to 1836-1840, with sections designed by the railway engineer George Stephenson and his son Robert.
Emily Gee, head of designation at English Heritage, said: “After carefully examining the documentary evidence and the structures themselves, several bridges, viaducts and tunnel portals along the line will be strong candidates for listing.”
English Heritage, in cooperation with Network Rail, is assessing 45 structures that will be affected by the electrification.
Councils, the Victorian Society and the National Railway Museum are among bodies being consulted, as well as the public.
