This paper surveys developments in several new rail transport systems, combining the principles of Magnetic Levitation (maglev) and linear motor propulsion, with special reference to the Transrapid system. The integration of such maglev systems into the existing transport infrastructure is expected to reduce road and air traffic considerably, thus improving the quality of passenger and freight transport after the year 2000. The two most extensively investigated types of Maglev technology are: (1) based on generating eddy currents; and (2) use attractive forces between magnets in the vehicle and reaction rails on the guideway. Maglev systems are described, that are being developed in the UK, USA, France, Japan and Germany. The Transrapid system, developed in Germany, is the most advanced system for guided ground transport, and is capable of commercial operation at speeds between 100 kph and 500 kph. Its first application is planned on the Berlin to Hamburg high-speed route. The paper gives a technical description of its subsystems, and discusses its: (1) environmental compatibility; (2) performance characteristics; (3) availability; and (4) safety. Finally the system's profitability and application fields and projects are reviewed.
