The Baikal-Amur Highway (BAM) runs through the territory of the Irkutsk Region, the Trans-Baikal Territory, the Amur Region, the Republics of Buryatia and Sakha (Yakutia), and the Khabarovsk Territory.
History
2024: How is the digitalization of the Baikal-Amur Railway 4300 km long and worth 17.7 billion rubles
Russian Railways is introducing a laser scanning system on the Baikal-Amur Railway (BAM) with the ability to build 3D models of cars and virtual coupling technology. The digitalization of the railway with a length of approximately 4300 km is described in the materials of the resource "Russian Railways Digital," which TAdviser got acquainted with in mid-July 2024.
In 2024, it marks 50 years since the start of active construction of BAM. This railway in Eastern Siberia and the Far East has become one of the most difficult and important projects in the history of Russian Railways. When creating the highway, the latest technologies were used, advanced methods of construction and operation were developed and patented. The implementation of the project cost the state, excluding lost profits, 17.7 billion rubles (in estimated prices as of January 1, 1991). As of 2024, there is an active introduction of digital technologies.
Automated systems for commercial inspection of trains and cars with laser scanners (ASCO PV 3D) are installed at BAM stations. The complex allows you to track hundreds of parameters without stopping the composition. The system uses numerous sensors, sensors, laser scanners and video cameras installed on special frames at entrances and exits from stations. Based on the obtained data, a 3D model of each car is created in real time. This makes it possible to detect various violations, displacements, etc. Scanners make it possible to significantly reduce the time of inspection of trains. The system operates in a wide temperature range - from minus 40 to plus 40 degrees Celsius. At the same time, the compositions can be scanned while moving at a speed of up to 60 km/h.
Under the digitalization program, the Virtual Coupling project is also being implemented. We are talking about the technology of interval regulation of train movement, which provides synchronous movement of the following two freight trains along the way with the minimum permissible distance from each other. Data exchange between locomotives is carried out over a secure digital radio channel. In other words, two freight trains are connected into one train controlled by an intelligent system of automated movement. It is claimed that the technology allows you to reduce the interval of passing freight trains to 4-6 minutes, which significantly speeds up train traffic. Moreover, "Virtual Coupling" can work not only with two, but also with three compositions.
In addition, special sensors for monitoring sedimentary deformations and displacement of the roadbed are being introduced at BAM. They are used in those areas where thawing of permafrost soils is observed. The technology provides monitoring with the required frequency and high accuracy. This eliminates the need to perform the corresponding operations manually. Such sensors can be used in other railway processes.
The project "Construction and modernization of the" last mile "sections using fiber-optic communication lines" is replacing the existing copper lines with fiber-optic ones. This allows you to increase the bandwidth of data transmission channels from 2 Mbps to 1 Gbps. By the end of 2025, it is planned to implement a digital monitoring system project based on the Internet of Things. Import substitution of information platforms is actively underway. In addition, an electronic logbook of brake shoes, an electronic technological process of the station, a technology of electronic coordination and approval of technical and administrative acts of the station and technological processes are being introduced.[1]
