Glenfield Tunnel
The Glenfield Tunnel, built in 1829, was one of the world's first underground rail routes used by steam trains to carry coal from North West Leicestershire's pits to the city.
It shut in the 1960s when British Rail sold it to Leicester City Council for £5.
Leicestershire Industrial History Society (LIHS) arranges tours on a variety of dates throughout the year. For more information go to Leicestershire Industrial History Society website
