Blea Moor Tunnel is 2,629 yards (2,404 metres) long and it is the longest tunnel within the Settle Carlisle Railway Conservation Area (SCRCA). At its deepest point (between shafts 2 and 3), the tunnel is approximately 500 feet (152 metres) below the ground surface.
This Location Record is for the underground section of the tunnel and the geolocation data (latitude & longitude) relates to the approximate mid-point between the two tunnel-mouths. Construction involved the sinking of at least five separate shafts, three of which have been retained to provide ventilation (see 'Associated Locations' below).
