Digital Train Traffic Control System with Perfect Level of Diagnostics and Monitoring: Virtual and Radio Interlocking

This paper reviews a state-of-the-art architecture of the train traffic control and monitoring system. The architecture implicates fitting each peripheral object-level controller of railway automation equipment with diagnostic modules, assignment of diagnostic circuits and computing cores to perform diagnostics and monitoring. The following control system designs are described: both centralized and decentralized arrangement of equipment. The paper draws attention to possible uses of cyber-protected channels for control over decentralized railway automation facilities, and the collection of diagnostic data. New types of decentralized railway traffic control are described: radio interlocking and virtual interlocking for switches and signals. Proposed the architecture of the control system as a service function with available benefits of the above technical approach compared to existed analogues. With developing technologies of traffic control routing from a traction vehicle itself will become available in the future.
