Increasing speeds on existing railway lines is one of the main challenges facing the Belarusian railway. Through the territory of the republic there are two transport corridors connecting Russia and Western Europe, as well as Ukraine and the Baltic countries. In all of the above countries, the increase in speed on the railways is very fast. Belarus can not stand aside. However, to increase the speed, it is not always enough initial information. To identify the necessary data, methods of decision theory are used. The integral probabilistic criterion method (CPI) allows one to substantiate the road parameters necessary for introducing high-speed traffic on existing lines. The proposed method of decision-making on the choice of technical parameters and equipment of the line, taking into account the uncertainty in the re-design for the high-speed movement of passenger trains. The initial data for determining the CPI is a risk matrix or a matrix of particular criteria. When using the risk matrix for each design decision option i, the dependences of the expectation of losses on the probability of realization of the design conditions p varying in the range from 0 to 1 are compiled. In the article on the proposed methodology, the reduced costs for the variants of design solutions are determined under all possible design conditions. Using these costs, a matrix of private criteria and a risk matrix are formed. A comparison was made of the design decision options for the integral probabilistic criterion, using which the recommendation of choosing the option is unambiguous and is accompanied by a quantitative assessment, which facilitates the task to the decision maker.

The integration of the railways of South and North Korea will make it possible to form an international Eurasian transport corridor and ensure the transportation of goods produced in the Republic of Korea by rail. Today, South Korean cargo owners, due to the island situation, use mainly sea transport. The organization of transportation on the Trans-Korean Railway with access to the Trans-Siberian Railway and the railways of China and Mongolia will give advantages to shippers in terms of cost and time of cargo delivery. The implementation of the project on the reunification of the Trans-Korean Railway will lead to an increase in the volume of cargo and container transportation, including in rail-sea communication. In the Republic of Korea, the main transport hub is the port of Busan, which is served by rail and road transport. The Busan transport hub includes two seaports - the new and old Busan ports, railway stations serving the container terminals of the port, as well as rear terminals to which container delivery is carried out by road. Every year, the share of rail transport for the import and export of containers to the terminals of the port of Busan is less than 7 % and continues to decrease. This dynamic is associated with the presence of infrastructure, economic and technological problems of interaction between rail and sea transport in the port of Busan. The subject of this study is the analysis of the processes of interaction between different modes of transport in the new port of Busan. The purpose of the work is to develop measures to increase the capacity of the railway component of the Busan transport hub for the organization of trans-Korean transport within the framework of the Eurasian transport system. In this paper we used theoretical methods of research, including a systematic analysis and synthesis of information. As a result of the analysis of the technical equipment, operating technology and the existing railway infrastructure of the New Port of Busan, the presence of «bottlenecks» in the functioning of the «railway - seaport» system was revealed, which hinder the effective process of container transportation. The paper considers infrastructure, technological and organizational measures to increase the processing capacity of Busan transport hub facilities. The implementation of the measures under consideration will require time to change and restructure the system of interaction of transport in the process of container transshipment. It is necessary to determine the stages of infrastructure changes based on the forecast of future traffic volumes, including using simulation modeling.

The article shows the relevance of the problem of noise pollution of the environment by railway transport. The purpose of the research is to assess by calculation and instrumental methods the compliance of the existing noise levels in the residential area near the railway tracks with sanitary standards, to propose a set of noise protection measures and to substantiate their acoustic efficiency. The applied methods for measuring and calculating the equivalent and maximum noise levels of the rolling stock comply with the requirements of regulatory documents. The authors took into account the features of the propagation and shielding of sound waves in the existing residential area, background noise, and the traffic intensity of trains of various categories. The results of measurements, calculations and estimates of the noise generated by the rolling stock in the residential area in Omsk are presented. A significant excess of the maximum permissible equivalent and maximum noise levels in residential areas has been established. Comparison of the calculated and measured noise values, taking into account the standard uncertainty of the calculation methods and the expanded measurement uncertainty, showed quite satisfactory convergence of the results obtained and confirmed a significant excess of the sanitary noise standards. A set of measures is proposed to reduce the noise of railway rolling stock at the source of its occurrence and on the path of its propagation in the existing residential area. The dimensions of the embankments of the two sections of the railway tracks allow the installation of screens of low height up to 38 cm, the geometry of which is designed so that, in terms of reflection of the noise emitted by the rolling stock, they are at least equivalent to a standard noise protection wall 2 m high. For the track section located in the recess, it is proposed to install a noise barrier 6 m high and at least 1 km long. Its acoustic efficiency was calculated.
