Solution
- We know that air moves from higher to lower pressure region.
- Also when a train moves with high speed it creates a region of low pressure.
- Therefore, the air pressure behind the person becomes higher than the air pressure between the person and the train.
- Due to these pressure differences, the force acts on the person towards the train and pushes the man towards the train.
- Thus, people are advised not to stand near fast moving trains.
