Study on Technology System and System Integration Method of China High-Speed Railway

Since 2004, China had launched the construction of a large-scale high-speed railways network, China had developed a set of mature, reliable technology systems and system integration method for high-speed railways with relatively low cost in a comparatively short time period. The special demands for highspeed railways in china were analyzed firstly, and then the structure and characteristics of the technology system of China high-speed railways were presented, as well as the system integration method. At last, the development trends of China high-speed railway technology are proposed.
