Cowburn Tunnel

The Cowburn Tunnel is a railway tunnel at the western end of the Vale of Edale in the Derbyshire Peak District of England. The tunnel is 3,702 yards long. It is the deepest railway tunnel in England, at 875 feet .
The Midland Railway began work on the Hope Valley line between Sheffield and Manchester in 1888. The tunnel was engineered underneath Colborne, part of a 1,700-foot moorland between Kinder Scout and Rushup Edge. The Midland awarded the tunnel contract to J.P. Edwards of Nottingham. Construction work started in October 1888 when a ventilation shaft was sunk in Cartledge Meadow near Edale. Tunnelling also started at the other end near Chapel-en-le-Frith and the breakthrough between the two sections was made on 18 July 1891. The lining out of the tunnel and laying of the rails was completed by March 1893, when the workmen were dispersed.
