freight trains from the Buxton area that supply material to power stations on the National Grid are to be diverted during maintenance work.
Dove Holes tunnel, on the freight-only line between Peak Forest and Chinley, is to close for nine days between Christmas Eve and January 2 while Network Rail carries out track and drainage renewal.
The closure means up to 24 freight trains a day, with as many as 22 wagons each, will be diverted via the passenger line between Buxton and Stockport. The £4.4m project is essential because the line serves a number of quarries in the area that power stations rely on for regular rail deliveries.
Staff and contractors will access the railway at Chapel-en-le-Frith station to carry out the work.
Locals have been assured that a large area of agricultural land used by contractors will be restored to its original condition following representations by Chapel man Edward Bradbury.
