Abstract: Based on a brief review on the railway development,the point of view that the key strategy for maintaining and improving the competetivity of railway in 21th Century is to transfer the railway transportation system to the railway intelligent transportation system (RITS)through the intellectualization on basis of infprmativization is put forward. The definition, features and general structure of the RITS is given and followed by the architecture and pattern of the development of RITS in China and the key technologies for constructing the
RITS of China.

Key words: Intelligent transportation system, intelligent system, railway intelligent transportation system, transportation
