  • Patent number: 5199358
    Abstract: The invention is a novel transit system in which vehicles are piggybacked onto electrically operated upper sled modules for longer distances or between critical high volume areas such as city centers and airports. The front wheels of the Electric vehicles (EVs) in this system are carried on an upper sled module which is connected by a strut or fin to a lower airfoil wing travelling in a generally below grade duct or conduit. The EV uses its own power to move the articulated unit from co-axial AC and DC motors supplemented by a parallel power supply and signals system. Vehicles mounted on the sled units are automatically spaced in response to central computerized timing and speed controls so as to ensure proper separation of vehicles using the guideway. Piggy backed vehicles can quit the guideway at predetermined nodal points to revert to conventional vehicular travel on the public highway system.
