Abstract Abstract：Research purposes： In this paper, by taking the particularities on medium and low speed maglev traffic as the research object, the author advanced the research of three typical structure forms in current domestic and international of medium and low speed maglev traffic industry, introduced the technical features, the important components and the key points concerning the design and have a brief analysisofengineering adaptability on this basis. In order to provide a reference to improve the track structure design in medium and low speed maglev transit, further analyzing and realizing the system featuresand working characteristics of track system for medium and low speed maglev transit.
Research conclusions：（1）Generally, track system of the low speed maglev transit system includes rail equipment and its supporting structure, and composition of the section in structure of " T " shape, the key point for reasonable form of track structure design is a good deal with the relationship between rail and rail beam; active control of magnet/rail relationship have a decisive influence to the design of the track system; maglev system's stability require big quality, large damping and small deformation; small clearance suspended on the track system raised strictly and precisely requirement.（2）For the actual engineering application: the track of HSST system has more practical application experience, but was unable to realize the flexible adjustment of F rail; the bad economy of non-sleeper direct track connection; monolithic ballast track realized the highly structure integrity and good geometry properties by setting the new adjustment layers and deck type fastener system, all of above meet the requirements of the technology in low speed maglev traffic system.（3）The research results can provide references for the track design of the medium and low speed maglev traffic operating lines.

Key words： Key words: medium and low speed maglev transit；track structure；High Speed Surface Transport(HSST)；magnet/rail relationship；electromagnetic force
