Nosikov S.V., Demyanov V.V. Мodernization of power supply devices of auto lock signal point. / Molodaya nauka Sibiri: ehlektronnyj nauchnyj zhurnal [Young science of Siberia: electronic scientific journal], 2021, no. 2(12).
The statistics of failures of automation and telemechanics equipment of the distance control system of the East Siberian railway is analyzed. A comparative analysis of the technical efficiency of obsolete overvoltage signal point protection devices and Barrier-ABT equipment has been carried out. It is proposed to modernize the automatic blocking signal point devices with voice frequency track circuits by replacing obsolete overvoltage protection devices with key protection equipment of the Barrier-ABT type. It has been established that due to the use of the Barrier-ABT protection equipment, the service life of the equipment is significantly extended, which leads to a reduction in operating and technical costs
