Abstract The article refers to the problems of operating the earth in difficult conditions. Railways in difficult conditions, especially in areas of permafrost and deep seasonal freezing of soils, need constant supervision over the operational performance of the track superstructure in plan and profile, as well as the state of the subgrade from the adverse and destructive leverage of external factors of a natural and technogenic nature. Sections of the roadbed, being deformed for long periods of time, require significant operating costs and capital investments to ensure the stability of these sections.
