An underground counter bombardment facility, with gun crew ready rooms, ammunition supply and engine room together with a narrow-gauge tramway which was cut into the sandstone and lined with sandstone and a large battery observation post were also constructed at the battery.
[1] The tramway was a single track of 560mm (22 in) and was to transport the 6" projectile munitions to the shell expense stores/magazines in the base of each gun emplacement.
The tramway traverses through a deep continuous cutting lined with sandstone leads from the ammunition drop off point to the basement of the ammunition supply room and up to the two gun emplacements.
Before reaching the gun emplacements the line enters a rectangular section concrete tunnel which is 94 m (310 ft) long.
Following decommissioning of the gun emplacements after the war, the site fell into disrepair.
