A single ventilation shaft, accessible via the moorland north-west of Mam Tor, is deep, making it one of the deepest railway ventilation shafts in the country. The shaft was constructed in 1894 over the course of two years. Men lived on the rough exposed moorlands to dig the shafts without any modern machinery and were lowered into the shaft using a winch mechanism. 102 men worked eight-hour shifts day and night to excavate, mason and brick the shaft. It was eventually completed on 16 March 1896. Currently the shaft remains open, but protected by a large brick enclosure (pictured).
