MoD to sell WWII Tube station command bunker The station closed 28 years later due to under use, but in 1938 the War Office bought the above-ground building along with lift shafts, stairs and some of the lower passages. The disused platforms are closed off and still belong to the Tube. The building became headquarters of the Army's 1st Anti-Aircraft (AA) Division, protecting the capital and surrounding areas. Floors were built into the lift shafts to create operations rooms complete with a telephone exchange, pneumatic tubes to carry messages and a huge table map of southern England. Information on approaching German aircraft reached the station from radar stations and observers, and was sent on to fighter squadrons and anti-aircraft batteries. There are also unconfirmed stories that Rudolf Hess, Hitler's deputy, was questioned at the station after he flew solo to Scotland in 1941 in an attempt to negotiate peace. The building was used for anti-aircraft operations until the early 1950s, by which time the Second World War defences were considered obsolete. The site now houses the London University Air Squadron, the London University Royal Naval Unit, and 46F Squadron Air Training Corps. An MoD spokeswoman said the units would be found new homes before the sale in September. John Taylor, estates surveyor for the Defence Infrastructure Organisation, which looks after MoD property, said: "The MOD keeps the size and location of its bases under constant review to ensure the Defence estate is no larger than necessary to meet operational needs and provides value for money for the taxpayer." The MoD is selling off several historic buildings in London, including the Old War Office in Whitehall which is expected to fetch more than £100 million and become a luxury hotel.
