A track has an acceleration zone and an inertial running zone. The acceleration zone is to accelerate a car lifted by a lifting apparatus having a stationary power source through a steep down slope. The track is disposed approximately horizontal in the inertial running zone as the car proceeds mainly by inertial running. The car is provided with a seat as to oscillate corresponding to gravity and acceleration of the car. A control device is used to control the oscillation of the seat provided. The seat oscillates corresponding to gravity and acceleration in lifting by the lifting apparatus and in the acceleration zone.
A transportation system is provided, in which a light-weight, small-sized vehicle can be used. This transportation system comprises a rail extending between stations, vehicle capable of running on the rail and carrying a drive unit, first zone for accelerating the vehicle from a stopped condition to a required speed by a propulsion force supplied from a propulsion supply unit provided from one of the stations toward the other station by a predetermined distance, and a second zone not having the propulsion supply unit, in which the vehicle accelerated in the first zone travels on the rail by the propulsion force supplied from the drive unit.
