PURPOSE: A device for dispersing gravity of a train is provided to reduce the weight of air pressing down the body of the train by dispersing the air pressing down the train. CONSTITUTION: In a device for dispersing gravity of a train, a plate of the upper part of the train is formed in a shape of capable of excellently dispersing gravity. If the angle for dispersing the air pressing down the train is sharp, the gravity of the train is reduced much effectively, but the device for dispersing gravity of the train needs not be installed so highly because the gravitational acceleration of air is just 9.8m/sec. Thus, the weight of the train is reduced and fuel needed for running the train is reduced.
