The article considers the problem of the behavior of the railway roadbed in geodynamically active regions using the example of the section of the Trans-Siberian Mainline of the East Siberian Railway from Biryusinsk station to Gorkhon station. When considering the scheme of the fault block structure in the south of Eastern Siberia, it becomes obvious that the Trans-Siberian Railway often crosses areas with tectonic faults. When studying the literature on the operation of engineering structures, one can trace the influence of movements in zones of tectonic disturbances on such structures as tunnels, pipelines, hydroelectric power plants, reservoirs, and embankments. The existing regulatory documents, considering the influence of exogenous and endogenous geological processes on the railway track, were analyzed. A classification of tectonic movements of the earth's crust and various types of tectonic faults is presented: faults, reverse faults, thrust faults, strike-slip faults and nappes. The main defects and deformations of the roadbed were discussed. The regulatory documents for the design and operation of the roadbed were analyzed, from which it becomes clear that the influence of tectonic movements on the roadbed is not reflected in any way in the regulatory documents. A comparative analysis of the location of roadbed deformation areas with areas where railroads cross zones with tectonic faults has been performed. On the basis of this comparison, a conclusion was made about the coincidence of the deformed roadbed sections with zones of tectonic faults. A conclusion was made on the decrease in the roadbed performance indicators in the zones of tectonic disturbances, and the need to improve the regulatory framework for the design and operation of the roadbed in these zones was proved.
