There is nothing that is specifically designed to keep the air pressure low under a train. A train is kept on the tracks by gravity, nothing more.
Pressure underneath a moving train is lower because of the Bernoulli's principle, which states that as fluid (such as air) moves faster, its pressure decreases. The train's movement creates airflow beneath it, causing the pressure to drop.
A low pressure under a train helps to minimize the drag force caused by air resistance, allowing the train to move more efficiently. It also reduces the risk of creating a partial vacuum underneath the train, which could impact its stability.
because if not then you have friction and friction causes massive problems

Activities include people, climate and technology; three factors that have a thoughts of their own. An knowledgeable adviser knows how to fix issues under pressure and stay relaxed under pressure. Ask them to discuss a number of "behind the scenes" experiences with you and how they managed them.
this is because sleepers increase the area on which pressure of train is to be exerted.Thus pressure is not concentrated on a single point densely.therefore if there more area there would be less pressure and train will run smoothly
You could get put under pressure to do something.............mannn
no
i think only 2 things effect on sound under water, temperature and pressure.
Three things you can do to protect yourself in a convoy under combat conditions is to: - Maintain standoff - Stay observant - Avoid setting patterns
A solution under a high pressure
They had bread, religious freedom and almost no limit on advancement.
