Abstract: The present invention relates to a transportation system wherein transportation means travel simply through the principle of a free fall by gravity, without using power, to carry or transport objects such as humans or freight. The transportation system of the present invention comprises a heavy object load station, a rail and transportation means. The heavy object load station is formed on undulating ground to easily utilize the force of gravity, and supplies heavy objects to provide the force for drawing the heavy objects in one direction in which gravity pulls. The rail supports vehicle wheels to reduce the running resistance of the vehicle wheels.
