Purpose. The scientific paper has a purpose to choose rational technological parameters of the transportation organization process, which would enable the freight train movement with the most efficient train traffic arrangement, the decrease in idle time due to the increased speed of cargo delivery and the increase in the working capacity of the marshalling yard. Methodology. The work presents the technical and operational characteristics of marshalling yards in Europe and Ukraine. The research methods include the station operation analysis, the car traffic flow analysis, analysis of the train sheet, the DU-1 natural sheets upon arrival and departure of trains. Schemes were developed for calculating working capacity of necks, rehandling capacity of marshalling hump, acceptable levels of system loading. Findings. The research resulted in the calculated working (rehandling) capacity of the main elements of the station. Daily loads of marshalling hump and turnout tracks vary significantly by variations and gradations of movement volume. This affects the idle time of trains and, in general, the value of the criterion according to which the optimal technical equipment, optimum interaction of the subsystems and gridiron of the station will be chosen. This criterion must take into account the costs of technical equipment, construction of tracks, locomotives, as well as related operating costs in all cases. Thus, the selection of the optimal interaction should establish the economically viable level of operational reliability of the sub-systems, their technical and track capacity. Originality. By increasing the productivity of train departure channel, marshalling hump and turnout tracks it is possible the thetrain handling processes and reduce the car idle time. Intensification of production processes in marshalling yards provides a reduction in car turnover and in idle time and high economic efficiency of capital investments. The work covers the issues related to improving the efficiency of functioning of marshalling yards in the railway transport reforming conditions. Practical value. Using the methods of determining the rational working (rehandling) capacity of marshalling yards for distribution of train traffic flows between them makes it possible to improve the quality indicators of marshalling yard operation.
