THE SIGNALING DIVISION 1520 GC INTRODUCED DIGITAL TRAIN TRAFFIC CONTROL ON THE Koltsevaya line of the Moscow Metro
Specialists of The Signaling Division and USC 1520 (a part of 1520 Group of Companies) have reconstructed and equipped the Koltsevaya line of the Moscow Metro with the Russian digital signaling system.
The new equipment will allow reducing the interval between the trains by 10-14%. During the rush hour 36 pairs of trains will be running along the line instead of 34, and the cars will become less crowded. The efficiency of dispatching staff will increase.
"The Moscow Metro is one of the busiest in the world. The network of lines is continuously developing due to the construction and modernization of infrastructure, passenger traffic is growing. With high traffic volume the latest digital train control systems will ensure reliability and safety of transportation, guarantee uninterrupted operation of the equipment," - said Konstantin Khromushkin, Deputy General Director of The GC 1520 for Innovative Development and Digital Transformation.
Instead of outdated relay devices of 1954, modern computer-based systems of track circuit control, interlocking, dispatching and automatic diagnostics were installed on the Koltsevaya Line.
"Installation of innovative digital equipment of The Signaling Division 1520 GC on the Koltsevaya line of the Moscow Metro optimizes infrastructure of the mass transit transport, enables transportation process to be carried out with maximum efficiency in order to improve transport service conditions. Travel time is reduced, personal time of Muscovites and guests of the capital is freed up. Comfortable environment and quality of life are improved," said Alexander Dmitrenko, Head of Mass Transit Transport at 1520 Signal Company.
Metro staff will be able to manage switches and traffic lights, control equipment parameters, make routes and regulate traffic schedule more efficiently. The level of cybersecurity will increase.
In addition, new power equipment for the traction substations of the Koltsevaya line was installed during the reconstruction, which will ensure a reliable power supply for the automation. Wire communications networks, fire and security alarm systems with automatic gas fire extinguishing, ventilation and air conditioning systems were reconstructed. Specialists performed most of the construction and installation works without stopping the line. They only had to partially change the train traffic route for the time of switching the equipment.
The Metro digitalization started in April 2021. The Signaling Division 1520 GC specialists installed their own computer- based interlocking system in the "Sokol" depot. The Koltsevaya line of the Moscow Metro was opened for passengers on January 1, 1950. The line consisted of 12 stations with the operational length of 19.4 km. The total length of automated line block (295 track circuits) is 38,8 km. The minimum inter-train interval is 90 seconds.
