On August 4, 2022, the project of Lengiprotrans JSC (part of the 1520 Group of Companies) for the reconstruction of the Rudny - Checkpoint 1303 km section with the construction of the second main track received a positive conclusion from the Federal Autonomous Institution "Glavgosexpertiza of Russia". _one_
The single-track section Rudny - Checkpoint 1303 km, 9.2 km long, is located on the electrified section Kandalaksha - Olenegorsk of the main line Volkhovstroy - Murmansk of the Oktyabrskaya railway. The implementation of the project will increase the throughput capacity of the section and ensure the growth of cargo traffic to the operating and under construction ports of the northern part of the Kola Peninsula. _one_
The design solutions provide for the elimination of Checkpoint 1303 km with the construction of 11.8 km of electrified main track II and the reconstruction of the Rudny siding into a waypoint. Work is also planned to reconstruct the existing I main track, contact network, and signaling devices. At the approaches to the Rudny post, along the axis of the new main track, a metal railway bridge across the Kuna River with a length of 65 meters will be built. _one_
Razezdny Rudny is transferred to a track post with the reconstruction of 2 main tracks, the construction of a heating point for track fitters and an EC post with the replacement of relay interlocking with a microprocessor-based MPTs-EL.
Work on the construction and reconstruction of tracks on the stage Rudny - Checkpoint 1303 will be carried out without stopping the movement of trains in 3 stages with the organization of a temporary bypass.
Design management was carried out by the chief engineer of the project of the department of surveys and design of railways Alexander Nikolayevich Bulatetsky. _one_
