I saw 2 programmes last year , on e was Blue Peter , the other was presented by Bill Bryson. The subject was London Underground stations that are no-longer used , but still preserved in the same state as the day they closed. Does anyone know who , what , where or how I can find out more about their locations??
One of them is Down Street opened in 1907 closed 1932 and was used by churchill and his many assistants (up to 60) during the war as a bunker. It's on the piccadilly line somewhere between green park and holborn
