Underground warning ballo / Underground warning ballon

Underground warning ballo

Some subway platforms have no security doors but only a yellow warning line, which has little warning influence. However, warning balloon will bring a feeling of movement when you wait and feel bored. The speeding train will produce suction, and it is very dangerous. Place warning balloon on the warning line, and it will be pulled to the train with suction. It gives a dynamic warning to make people away from danger area consciously.
