Abstract: This paper introduces the formation principle and influence range of the CBTC train safety protection envelope of Casco Urbalis888 system, and analyzes the mechanism for extension of the non-communication train safety protection envelope and its influence on the control of subsequent CBTC trains combining with the actual situation. According to the research, the corresponding management measures is provided in order to enhance the operational efficiency and reduce the impact of the failure, while there are failures to recover in the short term such as train losing communication, axle counter interference.
