Japanese trains are the most punctual in the world and they are also the most safe. One of the reasons why they are so punctual is that the same systematic protocols are accurately performed each time a train arrives to a station. Train drivers are trained to be able to stop a train within error margins of 10 cm in respect to the platform and 5 seconds in respect to the moment they are supposed to stop.
Some time ago in a Odakyu line platform I found this poster which explains that to become a train driver you need to spend 800 hours studying and training. I don’t know how much training is required in western countries to become a train driver, but 800 hours seem like a lot of hours to me.
In the poster they also explain how train drivers are trained to drive in a safe way. One of the biggest concerns of Japanese people is that if rail companies are too strict with their drivers, accidents may happen because the drivers are under stress, something that happened in Amagasaki some years ago when a driver was behind official schedule, took a curve too fast and caused the derailing of the train and the death more than 100 people. If the train had arrived late, the driver would have been strongly scolded.
