The scientific article formalized process improving the efficiency of rolling stock distribution in railways for loading goods by introducing concentration of loading at the terminal by using a dynamic model. Methodology. According to the experience, the distribution of rolling stock by the infrastructure operator is a complex process. The questions on transport expeditionary service, working technologies of separate subjects of railway industry and the question of forming organization principles of running carriages with different patterns of ownership are considered. The system of rolling stock distribution based on logistical control principles on railways should meet the next methodological criteria: reduction of empty run and waiting time under one freight operation, forming the correct informative area for all participants of the transportation, arranging conditions for rapid and maximally profitable decision-making as for the further movement of the rolling stock. Findings. Created a list of the necessary conditions under which there must be a dynamic development of the transport sector and meet the current market requirements. The algorithm and process logistic control allocation of railway rolling stock are considered. Proved that relationship between the participants of the transportation process of initial conditions for reform be composed based on non-discriminatory access to cargoes resources. Originality. The work of dispatcher staff in transportation process management as an employee of the transportation department in terms of demand for rolling stock at all stages of transportation management analyzed. For the first time proposed a dynamic model, that reproduces the information field for all participants in traffic. It established that the railways have to create a system of distribution of rolling stock, which must meet the following criteria: reduction in empty mileage and waiting time under one cargo operation; create conditions for rapid and most profitable decision for further movement of rolling stock. Practical value. Application of the developed method of rolling stock distribution for the formation of unit trains will significantly reduce the logistics costs in the supply chain and increase its competitiveness in foreign markets. The development of such a system is intended to create a truly independent regulator of the logistic – transportation process in the conditions of creation of the unified information space.

This statistics visually displays the level of operating consumptions, which connected with the infrastructure maintenance in waiting time. Taking into account a swift tendency to integrate railway industry into market conditions, which related to considerable reduction of the majority of the qualitative work indexes and deficit of budgetary investments, the guidance of the industry had to solve questions for overcoming this problem as soon as possible. The most important task is to create favorable conditions for involving investors and to set up preconditions for logistic infrastructure development. Purpose The scientific article formalized process improving the efficiency of rolling stock distribution in railways for loading goods by introducing concentration of loading at the terminal by using a dynamic model. Methodology The main regulations of a new law «On the railway transport of Ukraine» [1] worked out exactly for the solution of the question. So, it is planned to substitute the term «railway» into the new one « infrastructure operator», to form a new organ the National Commission on Transport Adjusting (NCTA) for correcting the rate compound and involving private ferrymen for transportation. Now days there are a lot of nonsolving problems which concern investment constituent, calculation of the railway rate (NCTA) without customer and others like that, but the obvious thing is to solve problem concerning the creation of equivalent terms for ferrymen in the real conditions of the operative transportation planning. Findings The distribution of rolling stock by the infrastructure operator is a complex process. A list of scientific sources that contain solutions to the problem of rolling stock management analyzed.
