The article considers the state of grain cargo transportation and related technical and technological problems. As a solution, the possibility of using multiple grain shipping containers and the introduction of a new modern grain cargo handling technology at the station based on inventory management and proper selection of vehicles was considered. The considered measures will contribute to simplifying, improving and reducing the number of cargo operations performed during grain handling, making their implementation more practical and energy-efficient.

transport may lead in the future to the loss by railways of part of the transportation market. This situation leads to the deterioration of financial and economic situation of the railway transport system. Determining prospective volumes of freight transportation by railroads will make it possible to choose the optimal model of behavior of transportation system. In this case, it is necessary to take into account the impact of the totality of economic, political, technological, natural factors, as well as the conditions of domestic transport market. As the economy in Ukraine largely depends on the operation of railway, then hasty management decision will have a negative impact on other industries. Without the ability to predict the future, it is impossible to organize normal func-4

The aim of the article is to define of rational technology for service cargo points at railway connecting lines of industrial enterprises taking into account possible penalties. To solve this problem, the authors used methods of analysis of statistical data of dynamically changing parameters, methods of simulation modeling, mathematical statistics, probability theory and methods of combinatorial analysis. In the work is formalized the rational technology for service at railway connecting lines of industrial enterprises in the form of a mathematical model. The objective function of the model uses the criterion of total operating expenses and takes into account the probabilistic nature of the waiting time for dispatching of wagons to the cargo point. The mathematical model is designed to determine the rational number of wagons in the dispatching to the cargo point at railway connecting lines of industrial enterprises. The proposed technology takes into account penalties for violation of the delivery time.

The article considers the effectiveness of the introduction of speed and high-speed traffic. The experience of foreign countries shows that the development of high-speed rail traffic has increased competitiveness between different modes of transport, population mobility, reduced the loss of passenger traffic by attracting additional passenger traffic and increased profits. The state of speed and high-speed passenger traffic in Ukraine is analyzed, the main factors influencing the possibility of introduction of such traffic are revealed. The main ones are: lack of state financial support and private investment for the modernization of the railway or the construction of specialized tracks, the purchase of special rolling stock. In conclusion, attention should be paid to improving the state of the railway infrastructure to increase the profits of the railway and the ability to further invest in the implementation of such projects.The method of determining the required investments from the sources necessary for the implementation of large-scale projects of public importance, which depend on the internal rate of return on the project, the internal rate of return in the industry and capital investment in the project. Economic justification of the expediency of the organization of high-speed and high-speed traffic in Ukraine is an investment project, which provides for a phased investment in construction, which will further receive annual profits from passenger transportation. To solve this type of problem, it is proposed to use the net discounted income that can be obtained during the project and after its completion. It takes into account the income achieved in a given year of calculation, the costs incurred in the same year, the discount rate set by the investor and the payback period of the project.If the demand factor for transportation fluctuates, it is possible to calculate the company's income for the following years and determine the payback period of the investment project.
