A high-speed ground transportation system wherein a vehicle rides on a film of air and is propelled as a free piston through a tunnel by pneumatic pressure. Seals on the vehicle create fluid communication between a high pressure area behind the vehicle and the area beneath the vehicle while preventing fluid communication between that high pressure area and an evacuated area located in front of the vehicle, to create an air film beneath the vehicle upon which it rides. Cargo handling means are located near the tunnel and shunting means enable the vehicle to be shunted into those cargo handling areas when desired. Booster stations located at selected points serve to increase a pressure differential across a vehicle to assist that vehicle when necessary, and magnetic means are used to maintain the vehicle in a upright orientation as it is propelled through a tunnel.
