This invention is a harness for automobiles in order to ride a modified magnetic levitation railing system. The magnets and superconductors are used to lift and propel forward the harness. The lift points are in order to keep the automobile level and keeping the automobile from moving around. The bolt holder is to keep the automobile, wheels, suspension, and shocks in place. The Bolt Holder R4 is a specially designed part to attach to the automobiles wheels, it has a bearing and thread in order for the part to spin freely and be secured onto the automobiles wheels. The frame is designed to accommodate most automobiles. The rail drop is there to have a path for the automobile to enter/exit the harness. The bearings are there to allow the magnets, superconductors, and the automobiles wheels to spin freely as it travels to its destination and at the destination.
