ISSUES OF MODELING THE OPERATION OF THE LOCOMOTIVE COMPLEX IN ORDER TO SUBSTANTIATE THE POSSIBILITY OF DEVELOPING PROMISING CARGO FLOWS IN THE EASTERN DIRECTION OF THE COUNTRY

The scientific study presents the results of a comprehensive analysis of the operation of the locomotive complex of the railway station of the Trans-Siberian railway. This station is a technical junction point for different current systems. The technology of operation is considered, taking into account the increase in the size of freight transportation by 30%, which is provided for in the Transport Strategy for the development of the railway industry until 2030. An analysis of the existing traffic sizes was performed and a simulation of the operation of the locomotive complex of the station in the new operating conditions was performed. To identify the “bottlenecks”, a simulation of the operation of a DC and AC locomotive complex was carried out, which is based on the technological time of arrival of train locomotives on production lines. A set of measures has been proposed for the reconstruction of the locomotive complex for the development of promising freight flows in the eastern direction of train traffic. The economic efficiency of the infrastructure modernization project has been calculated using the dynamic cash flow modeling method.
