This article, based on the study of local and foreign experience, identifies the need to seek comprehensive solutions for the effective organization of the wagon-flows in JSC “Uzbekistan Railways”. Based on the processing of statistical data, it was determined that the length of a group of wagons in a one direction multi-group train is subject to the law “Erlang”. Based on the use of Fibonacci numbers to search for the best scheme for the formation of multi-group trains, the method of determining the minimum required number of sorting tracks depending on the length of the group of wagons has been improved. As a result of the application of this method by JSC “Uzbekistan Railways” at station “Chukursay”, the cycle time of the sorting hill was reduced by 12%, the time spent on sorting of transit trains was reduced by 5% and the processing capacity of the sorting hill was increased by 14%.
