Abstract
The configuration of an interlocking system that autonomously operating on a per-track-circuit basis is presented. The system consists of safety-related and non-safety related functional parts. The safety-related functional parts are accomplished by units assigned to specific track circuits and a communication network between the units. This system is characteristic in that the desired function can be achieved by connecting the communication lines between the units according to the track topology in the station premises. This paper shows the range of interlocking logic achievable by this system configuration and presents the applicability of the interlocking logic to conventional station tracks.
