The development of national transport system impacts the performance of enterprises, and therefore, its viability in the market conditions. At the same time, the market is the exchange of goods and services, which is impossible without transport. Transport is a crucial component of the market infrastructure. It is essential to consolidate all the transport sectors into a multimodal transportation system, which would be convenient in terms of customer servicing, shipment time and accuracy, cargo safety, end-to-end information support, and financial relationships as well. Traditionally, the applied science deals with management of train and rail car traffic, stations, and rolling stock. In practice, carriers and cargo owners often have different priorities. The carrier needs to comply with routes and delivery time, while the customer is more concerned about shiploads, consistency in the delivery of carload shipments, and clearly scheduled delivery times. The problem of determination of ways to develop a unified transport environment facilitated by integrated multimodal transportation techniques is of a higher relevance. The purpose of this research is to identify certain stages of freight transportation, study the opportunities of applying various transportation techniques focusing on operating costs reduction, and to analyze the ways to improve routed transportation to the mutual benefit of both carriers and shippers. This work employs research methods to analyze freight transportation, and methods of mathematical modeling of the transportation process subject to introducing new techniques to minimize the number of re-classifications made on the route and reduce operating costs at unloading stations. As a result, the criteria have been identified to determine the choice of railroad transport operation activities subject to minimizing costs throughout the operating domain.

Timely relocation of empty cars to loading stations plays an important role in rail freight transport logistics. The purpose of the study is to determine the criteria for identifying a need for reserved station tracks while minimizing operating costs. The authors used special methods to study freight transport operations and mathematically modeled the transportation process subject to the developed technological measures, such as concentrating the car traffic at stations and yards with sufficient technical capabilities, minimizing the number of handling operations in transit, and differentiating cars according to their respective operators. As a result, the authors identified the criteria underlying the decision-making algorithm for managing rail transport operations, while minimizing costs throughout the service area.

The paper considers variants of different technologies of transportation process that are directed on minimization of operating costs and that consider mutual interests of a carrier and consignors of goods. At introduction of such technological measures as concentration of car traffic at stations with sufficient technical possibilities and provision of a minimal number of yard operations in transit with separation of cars by belonging to operators the authors have applied the operations research method and mathematical modeling of transportation process. As a result, the authors have developed a decision making algorithm on organization of operation with the consideration for loading of infrastructure in every design day.
