Physical-geographical factors of engineering-geological conditions were examined (orographical, hydrological, climatic conditions of the territory). Regional geological factors are described: geological structure of the area, rock formation of various composition and origin, hazardous geological processes and related phenomenas: weathering (physical, frost weathering), cryogenic (frost polygonal cracking, frost-heaving, spotting, ice build-up, snow patches, thermokarst); gravitation processes
(slides, landslides, solifluction); erosion processes (river, gully erosion, alluvial cones, sills); fluvial processes (water logging). Technogenic factors related to mining, transport and residential complexes were characterized. Typification of geotechnical conditions of Polar-Ural railway route corridor was carried out: the are of Sob river valley with subareas of valley complex of the river and its inflows with engineering-geological regions and subregions, subarea of modern water-dividing areas with engineering-geological regions and subregions is conducted investigations give evidence of the complex construction environment and operation of railway within the environmental conditions of Polar Ural. Organization of complex engineering-geological monitoring with the development of environmental measures is recommended.
