Top Secrets from the Underground

I don’t know many real secrets of the underground having never worked for them but I do know that at Manor House they have installed a new escalator (the middle one of three) and when it is running (which isn’t often) if you ride it you can race the other people going up. And you know what? You are going to win, because that escalator is super fast - you will overtake about 20 stationary bods without walking yourself. And strangely nobody else seems to notice this joy!
