Automatic Locking System with Tone Rail Circuits for Train Safety and Regulation

Microprocessor-based ABTC-MSH is a system of interval regulation and ensuring the safety of train traffic on the crossings. It performs the functions of monitoring the integrity and freedom of the rail track, control of train passage with logical control of the release of block-partitions, control of signals of track traffic lights with control of the integrity of lamp filaments, formation and transmission to the locomotive information about the train situation through the channels of automatic locomotive signalling ALSN and / or ALS-EN, etc. Construction of the system for a particular railway section is ensured by using modules that are functionally complete parts of ABTC-MSH. The number and nomenclature of the system components are determined at the design stage of a particular section. For installation in mobile complexes of railway automation, telemechanics and communication, smaller cabinets are produced.
