Postal underground

This is amazing.  Someone managed to find a way into the abandoned Post Office railway under London and took a raft of photos.

That's what I love about the Capital.  There are so many railway tunnels, bunkers, service ducts, sewers, underground rivers and whatnot down there that in the event of nuclear war we're guaranteed to spawn a race of telepathic mutants to hold off the apes when they take over.
