Denton Colliery was the largest of these mines and eventually absorbed the other local pits, often using their shafts for ventilation or, in the case of Hulmes Pit, as a pumping station to drain water from the main workings. Denton Colliery was connected to the London & North Western Railway's line from Guide Bridge to Stockport by a standard gauge tramway. The tramway was worked by steam power, rather than horses, as evidenced by a photograph held in the Tameside Local History Library archives.
