ABSTRACT: This report is an Executive Summary of FRA report 0R&D-75-21 which summarizes studies to establish the technology of repulsion magnetic suspension for ultimate use in a passenger carrying high speed ground transportation (HSGT) system - at speeds on the order of 134m/s (300 mph). A baseline revenue system is described in terms of vehicle/guideway configuration, system performance and cost. Levitation and guidance is provided by eight superconducting magnets. The magnetic fields interact with a pair of L-shaped aluminum guideway elements. Propulsion alternatives are discussed but this is the area where much work remains to be done to provide adequate performance and cost data for a final selection. This technology, designed to free ground transportation from the speed and noise limitations imposed by steel wheel on steel rail, will make possible the short trip times of planes with the huge capacity of trains. Both speed and capacity are essential to meet the demonstrated demand for rapid travel in the nation's congested corridors.
