Stairway to Breathlessness

I went on a tour of Aldwych station, which has been closed since the nineties. It is now used for training TFL staff and trying out new decor and features for other stations. It is also for used for filming. 
In both world wars it was used as a shelter for people and items from museums, including the Elgin Marbles. 
There are 130 steps down to the platforms, and unfortunately 130 back up again.
