International ClassB61B 013/00AbstractThe electromagnetic induction suspension and horizontal switching system for a vehicle on a substantially planar guideway provides vertical lift and stability and lateral stability for a vehicle. The system provides inherent vertical lift, as well as vertical and lateral stability, including pitch, yaw and roll stability. Moreover, the suspension and stabilization system of the present invention allows electronic, horizontal switching between multiple substantially planar guideways such as a mainline guideway and a secondary guideway, which may be accomplished at speeds over 300 m.p.h. Proximal to and within a switching area at the intersection of the mainline guideway and the secondary guideway, the respective lift and stability systems for each guideway coexist and may be switched on or off, depending on the path chosen for the vehicle.Other References
