Abstract: Intelligent Railway System (IRS) belongs to the research area of rail traffic in Intelligent Transportation System (ITS). Many Chinese experts and scholars are studying the intelligent transportation system including IRS and many achievements have been gained. In this paper, the development of Intelligent Transportation System (ITS) and the research about Chinese Intelligent Railway System (CIRS) is presented. The basic formations and the general structure frame of CIRS is also discussed. At last, the key techniques of CIRS is discussed. The desire about CIRS in this paper can be consulted in developing Chinese Intelligent Railway System.

Key words: Chinese Intelligent Railway System, basic formation, the general structure frame
