Reliability Models for a Safe Train Traffic Control Systems Accounting the Railway Infrastructure States

The authors developed the advanced train traffic control system architecture. This architecture is based on the railway infrastructure facilities monitoring techniques integrated into the railway automation and remote-control equipment. Such system has a higher level of safety due to the transferring data about the infrastructure facilities state into control complexes directly without the "human – operator" link of the monitoring system. Data from infrastructure facilities that do not directly interact with railway automation equipment’s make it possible to quickly develop control actions for the timely developing defects counteract. The authors developed reliability models for the train traffic control systems, in which the railway infrastructure facilities states are considered. Authors presents the accounting the infrastructure complex safe state relevance in train traffic control systems. The developed reliability models using are advisable in the safe train traffic control systems development, as well as in railway infrastructure facilities digital twins developing include real-time modeling of processes.
