The paper describes a decision support system (DSS) for actions in conditions of a threat of track erosion for the Ulaanbaatar Railway. Information about the road is briefly presented, and the geoclimatic conditions of its operation are described. A mathematical model is given for kilometer-by-kilometer calculation of the threat of track erosion depending on the meteorological forecast, track condition and the presence of artificial structures. The composition of the DSS, its functionality and general principles of operation are considered.
