Fawley Tunnel is a 3-metre (9.8 ft) diameter, 2-mile (3.2 km) long tunnel under Southampton Water between Fawley Power Station and Chilling near Warsash.[1] It was constructed between 1962 and 1965 to carry two 400 kV circuits as part of the National Grid.[2] The tunnel was built with a 3 feet 1.125 inch gauge railway to help with maintenance access.[3] The railway was operated with a single battery powered locomotive that was scrapped in the late 70s.[3][4]
