Control of the Beginning of Accidents in Railroad Operation Safety Systems in Seismically Active Regions Using the Noise Technology

“…However, the seismic activity in some regions can create problems. The most important and vulnerable elements of rail transport are the moving part of cars and railroad tracks, the insufficient monitoring of the condition of which does not ensure the proper safety of the rolling stock [1][2][3][4][5][6][7][8][9][10]. As the railroad passes through seismically active regions, additional requirements for traffic safety appear.…”

“…This particularly applies to the problems of controlling the onset of the emergency condition of wheels and rails, their vulnerability and derailment conditions. Our analysis of the literature [12][13][14][15][16][17][18][19] devoted to control technologies and control systems taking into account the specific characteristics of railroads of seismically active regions has shown that the use of noise technologies [1] can indeed improve the safety of this mode of transport. To do this, it is reasonable to create a subsystem for noise seismic hazard warning [11], i.e., a subsystem for noise control of the onset of the initiation and dynamics of development of changes in the technical condition of the rolling stock and railroad tracks to incorporate in the existing railroad monitoring systems.…”

“…However, in spite of this, at the present time, there are often wrecks of freight and passenger trains. Therefore, as our studies have shown, by solving some problems, such as ensuring control of the latent period of changes in the technical condition of railroad tracks, railroad bridges, tunnels, crossings, individual cars, and the entire rolling stock, it is possible to enhance the safety of rail transport [1]. This is particularly important for rail transport in the countries located in seismically active regions.…”

“…For this purpose, extensive railroad communications with modern bridges, tunnels and stations have been built. This complex infrastructure is managed by many different modern monitoring and diagnostic systems [1][2][3][4][5][6][7][8][9][10]. These systems ensure a high level of efficiency and safety of rail transport.…”

“…They, as a rule, do not result in great destruction, but each such weak earthquake is a potential factor contributing to the beginning of the latent period of changes of facility's technical condition. In this regard, the development and creation of technology and noise control systems to ensure the safety of rail transport in seismically active regions and countries is of undoubted practical interest [1,11].…”
