Maglev trains use maglev technology to achieve support and guidance between vehicle and track, and realize propulsion and electric braking through linear motors. Its application scenarios include the urban maglev transit, the medium-speed maglev transit, the high-speed maglev transit, and the ultra-high-speed low vacuum tube maglev transit. This chapter gives the definition of maglev trains, classifies maglev trains from the perspective of levitation principle and propulsion principle, and describes the electromagnetic suspension (EMS)-type system, the electrodynamic suspension (EDS)-type system and the high-temperature superconducting (HTS) flux-pinning maglev system in detail. What’s more, this chapter reviews the development history and technical evolution of maglev train technology in terms of structure schemes for levitation systems, and introduces the three technological stages of the rigid body vehicle scheme, the magnetic wheel structure scheme and the modular structure scheme that the EMS-type maglev train has gone through. Finally, this chapter discusses the research and application results of high-speed maglev based on the relevant technology researches in Germany, Japan, and China.
