Bradway Tunnel
From Wikipedia, the free encyclopedia
Bradway Tunnel, 2027 yards long, was built in 1870 about 1 mile north of Dronfield, in Derbyshire, England.
It is at the summit of the Midland Main Line between Chesterfield and Sheffield, on what is known to railwaymen as the "New Road" which the Midland Railway built, diverting from the "Old Road" built by the North Midland Railway which bypassed Sheffield due to the gradients involved. During its excavation, a number of small heading tunnels were needed to drain some 16,000 gallons of water an hour.
At the north end is the triangular junction on to the Hope Valley Line and Dore station. Northwards the line proceeds down a 1 in 100 gradient, through the abandoned Beauchief, Millhouses and Heeley stations, into Sheffield Midland station.
