    I’m not sure. It has always been done like this here.

    I think it’s just a convenience thing. Might be useful in crowded trains, so people know which doors they should not stand in front of.

      It’s super important in Japan where jam packed trains are common during rush hours. They typically announce in Japanese and English, and may even have a visual displayed.
