The article considers options for stabilizing the thawing process of permafrost soil of railways during the reconstruction period. The analysis of the engineering and geological conditions made it possible to design rock cooling structures at this facility, which are berms and cover slopes of the subgrade with fractionated rocky soil. The technical characteristics of fractionated rock soil structures have been developed and tested in this cryological area and have shown their effective operation for more than 30 years. As a result of the operation of the railway embankment, permafrost degrades and its boundary is at different depths depending on local conditions and the condition of the drainage systems from the subgrade. The position of the upper permafrost boundary should be established during surveys, if it is not advisable to restore the frozen base to a depth of 10 m, it is necessary to strengthen the thawed weak base and create conditions for the consolidation of thawed soils.
