This was a failed explore as the tunnel's portals were tightly sealed making access impossible.
Humidity levels are high and temperatures stable - ideal conditions for bats. The structure is now a hibernaculum and has SSSI status. Although wet at its western end, Withcall Tunnel remains in excellent condition despite a 50-year absence of regular maintenance. The last train passed through on 17th September 1956.
