  1. I believe it shows you how long the particular train is in carts – rather nice as it ensures you won’t have to run if you end up in the wrong end of the station due to a short train arriving

  2. You’re standing at the white dot. The train are the red dots. This train is half the length of the platform.

  3. Total squares = the platform length
    Red squares = Where on the platform the train will be
    White arrow = Where on the platform the sign is

  4. It was a couple of years ago when I overheard a father explain what this was to his kid. I had no idea, and I have been taking the train my whole life.
