On the edge of a quarry, 200 yards along a track running west from Ladies Drive.
DEEMOLISHED In 2000 all surface features remained intact with the green paint flaking badly. The hatch was locked. The BPI pipe was surrounded by a square concrete plinth. There was a short post with a white cover over it, which could be a BT termination. The post was demolished in March 2004 and the site has now been quarried away.
Opened in 1961 and closed in 1991.
