ABSTRACT:
To provide a railroad car design that allows the car to travel at high speeds over current roadbeds at very low fuel costs per mile a special rail is formed. This rail has the form of a wave shaped on its top with the troughs and crests of the wave repeating themselves every several feet apart continuously down both tracks for the whole distance of the railroad. When a wheel of this multi-wheeled car comes over the crest of a wave it has encountered as it moves down this wave formed track, the wheel immediately begins supporting its computer calculated portion of the weight of the car on a cushion of air pressure forced into its supporting air cylinder at that moment and rolls down the face of the wave in its desired direction of travel. Upon reaching the bottom of the wave's trough and starting to roll up the up hill portion of the wave form, the wheel is pushed back up into its supporting air cylinder thus expelling the trapped air by the upgrade created as the track shade ascends back up out of its trough to form the next wave crest. To stop the car, the trapped air pressure in the extended air cylinder is not allowed to exit its cylinder as fast as it normally would as each wheel is retracting on the upgrade out of its wave's trough.
