With the merits of safety，economic，environment-friendliness，magnetic levitation (maglev) vehicle is the typical represent of advanced type of rail transit． High temperature superconducting (HTS) maglev vehicle which is based on the flux-pinning effect，and electrodynamic suspension (EDS) maglev vehicle which takes su- perconducting magnet as on-vehicle active cell are the main forms of superconducting maglev traffic． The structure， theory and development of two kinds of superconducting maglev vehicles were introduced，and their advantages and disadvantages were analyzed． On the basis of“high speed”developmental direction of maglev transportation，vac- uum tube HTS maglev and EDS maglev with HTS magnet instead of low temperature superconducting magnet will be the main trends for future high-speed transportation．
