Various high-speed Magnetically Levitated (Maglev) Transportation system configurations have been devised and advocated since its invention twenty years ago by two Brookhaven National Laboratory scientists. Although the United States stopped Maglev development in 1975-because of budget problems-the Germans and Japanese continued their efforts, and have today developed full scale Maglev demonstration systems. Neither of these demonstration vehicles, however, provide an economically viable solution for implementing Maglev along our Interstate rights-of-way. The guideway cost and, to a lesser degree, the vehicle costs are at issue here.A specific Maglev configuration was studied to determine the minimum cost design for this system. The results are presented to demonstrate how other Maglev systems should be studied. Evaluation criteria to compare alternate Maglev configurations are also presented.Utilizing the methods described in this paper will lead to the most economically viable and cost effective Maglev system. That system if implemented will satisfy the United States transportation needs well into the 21st century.
