The degradation of permafrost can induce geohazards such as thaw subsidence affecting the performance of railway infrastructures. For example, along an 800-m-long segment Russian North Railway (from Pesets to Hanovey railway station), some zones of thaw subsidence were studied in summer 2018. The subsidence can be as high as 0.5 m. Drilling, landscape zoning, near-field transient electromagnetic sounding, and electrical resistivity tomography were carried out to assess the underlying stratigraphy and permafrost conditions. Engineering and geological conditions of the site are complicated by the presence of permafrost. Soils can be in thawed and frozen state at the base of the embankment. The spatial arrangement of thawed and frozen soils is discontinuous. The thaw settlement is due to the snow accumulation along the road embankment which insulates the ground surface in winter and prevents further ground freezing.
