| Abstract: | The basic structure and working principle of radio-based cab signal wayside control system were described. In order to ensure its reliability, the system adopted dual controller architecture. The failures of individual controller are categorized and the reliability was analyzed by using Markov model in terms of the effects of the failure of each part on the whole system. The analysis results showed that dual controller architecture substantially improved the reliability of the system up to the specification of reliability. |
