Purpose. The work is aimed to assess the influence of locomotive service systems on the indicators of their use and operation organization of the locomotive depot. Methodology. To achieve this purpose the calculation of operational indicators of locomotives of series 2TE116 and TE33AS in the conditions of locomotive depot is performed. The simulation model of the locomotive repair shop has been improved. Using the methods of the queuing systems theory, simulation modeling of the locomotive repair shop with service and schedule preventive systems for locomotive service was performed. Findings. The program of locomotives repair at schedule preventive and service systems is calculated. Based on the simulation results of the repair shop operation, we compared the influence of operation and repair on the locomotive depot operation for two different approaches to the organization of locomotives maintenance. The simulation model of the locomotive repair shop allows further comparative analysis of the use of different series of locomotives in the depot. The analysis of the results obtained demonstrates that the proposed approach to modeling the maintenance and repair of a diesel locomotive fleet can be improved by determining the reliability indicators when locomotives arrive for scheduled and unscheduled repairs. Originality. We improved the simulation model of the locomotive repair shop, which allows analyzing the influence of operational factors on the system of locomotive repair, in order to select a rational system of the locomotive fleet maintenance. Practical value. The results obtained make it possible to analyze the influence of the operation and repair indicators of locomotives on the operation of the locomotive depot and to determine the feasibility of using the selected traction rolling stock at a given service area. The results obtained indicate that the use of TE33AS diesel locomotives with a service system should reduce the residence time for all types of maintenance and repairs.
