The World's Busiest Train Station

A nice documentary on the world's busiest train station -- Shinjuku in Tokyo. At some point I want to go to Japan for a whole variety of reasons, but I'd like to see how they run their system. I am not sure I want to go to Shinjuku and ride a train during rush hour. Maybe I would just sit, watch them and eat noodles.

Here is Part One. Part Two. And Part Three.
