And if you add one or two levels of magnitude of improvement, you will get the insanely good train system in Japan. Seeing 14 car 300 km/h capable shinkansens arrive on the same track in ~4 minute intervals in Hiroshima station (and elsewhere) is something to behold. And the commuter system is sometimes ever crazier, with many lines running parallel in the city center, large stations having dozens of lines, together providing huge capacity. No wonder around 8 million people commute to central Tokyo, 1.3 million of them through a single station (Shinjuku).
