Improvement work has been completed to upgrade a major track inside one of the world's oldest railway tunnels between Manchester and Leeds.

Network Rail has replaced 3km of track between Littleborough and Walsden stations which includes the lines inside the 180-year-old Summit Tunnel.

The Calder Valley line reopened on Monday 1 November after a nine-day closure so work could take place as part of a £2m Great North Rail Project Investment.


During the full railway closure Network Rail also worked with the Environment Agency to upgrade a culvert beneath tracks as part of its large flood defence project.

Karen Hornby, Network Rail's North West head of performance and customer relationship, said: "I'd like to thank passengers and local people for their patience while we upgraded tracks between Littleborough and Todmorden as part of the Great North Rail Project. The work will mean fewer train delays for passengers on the Calder Valley line and means the tracks inside the Victorian-built structure are fit for the 21st century.

"We're continuing our work in partnership with the Environment Agency to install a new culvert which will create a diversion for the Greenvale Brook beneath the railway."
