|Aldwych disused tube station - I visited in 2010|
I'll be watching - some of the characters on my usual journey to work, which involves a change from the Central to the Victoria at Oxford Circus are quite interesting. There is a mohecan sporting platform assistant, and one of the most weary, tired-of-life platform announcer you've ever met. "Pleeease don't block the doors, Ladies & Gents, it's not very intelligent"!
I moved to London in 1997 and since then I've had some truly bizarre experiences underground. Helping a pregnant woman who'd fainted and fallen backwards, smacking her head on the platform was one, witnessing a mugging another and then a full scale domestic argument in which all the sordid details of what each other had done with other people was regaled to the packed carriage.
And then my tour of Aldwych, the disused tube station, complete with actors in period costume to re-create the life people lived down there during the Blitz - there's nowhere quite like the tube.
