Annotation: The locomotive economy is one of the most important elements of the railway transport infrastructure, as well as one of the major subjects of the railway services market, which has its own regulatory mechanism, the components of which are the supply and demand for traction services. This article provides a broad overview of the work performed on the research topic and identifies the need for the development of theoretical and practical recommendations to determine the priority areas for the modernization of the locomotive economy in the system of Uzbekiston Temir Yullari JSC, taking into account the experience of developed countries. The performance of the main indicators of locomotive fleets is analyzed. Revealed, the main reasons for non-fulfillment of certain indicators of operational work. The goal of development and the stages of implementation of operational control systems for the dislocation of locomotives (OCLD) are formulated. In order to determine the economic efficiency and assess the functioning of the OCLD, simulation modeling of the operation of locomotives was carried out on the territory of the RRJ - Tashkent. On the example of a simulation model, it is substantiated that the operational control of the dislocation of locomotives makes it possible to increase the useful work of freight locomotives. It is proved that on the territory of RRJ-Tashkent will increase the useful work of freight locomotives by 3.83 hours from its actual value, the economic effect of which will amount to 2,161,167,920 sums per year.
