@gpvos - That doesn't always work. Sometimes a train will arrive early, but another train is scheduled to arrive before them, so they have to wait until the other train arrives and departs before they can enter the station, or they'll screw everything up. The train system in Japan isn't a single-line system, like the ones that exist in many cities. It is extremely complex, with express trains and trains that stop at every station all using the same platforms. The arrivals and departures have to be precise for the whole system to work.
