As you know, in the conditions of an unpaired train schedule at points of turnover and re-coupling of locomotives, it becomes necessary to determine candidates for dispatch or dispatch of locomotives in reserve. In this article, a technology has been developed to minimize the downtime of locomotives at points of turnover and re-coupling in conditions of their insufficiency or excess. In order to automate the process of identifying candidates for sending or sending locomotives, an algorithm has been created in reserve and a program for solving this problem on a computer has been developed. The developed computer program on the basis of the option with the minimum downtime of all locomotives automatically determines the candidates for sending or sending locomotives in reserve.
