Sometimes I've wondered what would happen to a person if they stood too close to the track when an express train went whizzing by. Some have discovered on their own, usually intentionally. Committing suicide by train is one way that some commit suicide in Japan. A friend of mine told me that is the way preferred by those who hate their families. You see, the trains run on a tight schedule. Thousands of commuters are relying on the train to get them to their destination or their connecting train on time. If you consider time equal to money, that is a lot of money if a train gets delayed. As you can imagine, someone jumping in front of a train could cause significant delays. Therefore, the railways companies charge the surviving family of the deceased a delay fee. Often the fee runs into the hundreds of thousands of dollars. So it is said that person hates their family if they commit suicide in such way. Very often it is discovered afterward that the person who did the deed had a beef with her mother-in-law over her husband or something to that effect.
This is platform and the railway is below. If you look on the left side of the photo on the left, you'll see a train approaching. A potential jumper would wait until an express train was passing by the station.
The photo below: in the foreground you can see how fast the train passes by and how close the platform is to the passing train.
