At present, the formation of multi-group freight trains in accordance with the established procedure at all marshalling yards of JSC Uzbek Railways is based on the experience of the relevant personnel. Therefore, one of the urgent tasks is to improve the process of forming such trains based on the introduction of modern technologies. This article presents the results of applying the Sologub methods and combinatorial sorting in the process of forming multi-group trains at the sorting station of JSC Uzbek Railways. The regularity of the dependence of the number of groups in a multi-group train on the required paths was also determined, and the effectiveness of the combinatorial sorting method relative to the Sologub method was also shown.
