The Transport Museum has long been a portal to secret sites in London, it runs regular tours of disused tube stations across the city, like Aldwych and the tunnels of Euston. Now you can explore Hidden London: the exhibition, an immersive trip that delves deep into the public transport underworld beneath our busy commuter feet and the stories hiding within it. Discover secrets from WW2 where a 2000-strong staff, mostly made up of women worked in an underground aircraft factory along a stretch of the Central Line. Peruse archive photos, previously unseen diagrams and vintage transport posters. The exhibition also includes a reconstruction of Winston Churchill's blitz shelter dining room.
