The paper considers modeling of effective structures of existing railroad embankments in several variants when projecting side tracks on the Baikal-Amur Mainline of the “Russian Railway”, PLC. The comparison of different factors affecting the temperature fluctuation in the roadway on a partially thawed permafrost subgrade was carried out by the numerical modeling in a non-stationary setting.
