"one of the best public transport systems in the world"

I agree with Kumaryu, I nearly fell off my chair when I read that. I too work in London/Tokyo... when I'm in London, I see WHOLE stations closed because of 'Elevator Malfunction'.... are you kidding me? And whole stations closed because of lack of staff, or whatever the reason of the day is, or the whole network shutting down due to strikes.... in my opinion London Underground is a joke; that a clity of such prestige and size as London has such a flaky transport system is a disgrace.
