It works! How's that even possible?
We were in Japan a few years ago. We absolutely loved it and we want to go back again in the near future. I noticed something fascinating in the Tokyo metro. In the most busy stations they have rectangles painted on the platform and in the rectangles there are lines drawn perpendicular to the train. The lines indicates where people are allowed to stand and wait for the trains to arrive. People enter the rectangles and patiently wait their turn. When the first rectangle in full people may stand and wait in a second one which is painted next to it. The first rectangle in labelled "first train" and the second rectangle is labelled "second train". When a train arrives the people in the first rectangle board the train and the people in the second rectangle move over to the first rectangle and wait for the next train. The crazy thing is - it works! How's that even possible? /Ake
