This paper briefly described the characteristics of urban rail transit, such as ,the linear motor subway, monorail, new transport system, light rail transit and low-speed traffic in regular magnetic and so on, a small cross-section of linear motor subway and non-adhesion driving, monorail transportation system for the overhead lines and vehicles which used rubber tires, new traffic system with the function of self-steering systems and unmanned, low-floor light rail transport system to facilitate the train ride down to meet the traffic environment of urban areas, low-speed magnetic levitation transportation systems usually with low noise relatively. Most of them cought select large slope or the small radius curve line, and they cought also be served as the supplement of large-capacity conventional subway, which have been attached by the world’s major cities for access to satellite, science and technology parks, and large residential or tourist attractions such as branch lines. Compared with the conventional metro vehicles, the difference of its basic structure is mainly manifested in bogie structure.
