This article provides an overview of dynamic models of the organization of railway freight transportation, in which the cargo flow is formed on the basis of the interaction of neighboring stations. Several configurations of a section of the railway network are considered and two approaches to the organization of the cargo transportation process are proposed, depending on the demand for them.

The greatest prospects associated with transnational rail freight are determined by the use of containers. In Russian publications, the development of containerized cargo transportation is mainly considered by analyzing the general laws of functioning of international transport corridors. At the same time, aspects affecting infrastructure diagnostics and analysis of the throughput capacity of sections of the railway network are not considered.The purpose of the study was to identify the characteristics of freight flows in the direction of the EU—EAEU—PRC, to identify infrastructure barriers that slow down the acceleration and increase in the volume of container railway freight transportation, as well as to develop a set of measures aimed at improving the competitiveness of container railway freight transportation along the transport corridors of the Russian Federation.In the course of the study, infrastructural diagnostics was carried out, which revealed a number of barriers that did not allow realizing the growth potential of transit container cargo transportation.To remove infrastructure barriers, it is necessary to implement a number of measures, the key of which are measures to increase the capacity of infrastructure at border crossings, increase the speed of trains along the railway networks of JSCo RZD, develop terminal and logistics centers that provide a wide range of services for consignors and consignees.The development of container rail freight is a strategically important area for the Russian Federation. The well-coordinated work of Russian Railways with private investors and the state in the framework of expanding and modernizing the terminal infrastructure, as well as increasing intermodal interactions, is able to overcome the existing infrastructure barriers and ensure the growth of container transit in the required volumes.

Based on China railway freight transportation network, this paper builds the railway transport network. Then, according to uneven distribution of capacity and the problems of asymmetric information, low efficiency of railway freight transportation, the paper puts forward the resolving method by whole network Christopher of the social network analysis. In this paper, according to the China railway transportation network statistics results of China railway freight transportation network Christopher, whole Christopher coefficient is 0.39. Originally, the study also concluded that the degrees of freight volume, using to finding out the problems of multiple nodes, sorting and take the strategy to improve group coefficient better. All in all, this paper solved the problem of China railway network understanding and gave advice for improving China's railway transportation economic benefits.

The sustainable development of geo-strategic transport networks plays a key role to meet the current expansion of the demand for commerce and economic growth. In this paper, a new geo-strategic railway network for freight services is designed with the purpose of meeting the needs of current and future demands for freight transport in the state of Santa Catarina, South Brazil. The freight flows of bulk cargo, containers, and refrigerated and liquid cargo observed in 2005 and 2015 and expected for 2023 have been analyzed and assigned to a fully connected railway network. The number of trains to meet all the demands has been identified. The links that would have a minimum number of daily trains running on them have also been identified and analyzed. New assignments are proposed and visualized using GIS. Next, location and technical specifications of specialized intermodal terminals focused on the customers’ and operators’ needs are discussed. The study shows that technological specifications for terminal operations play an important role when dealing with multiple freight types and contribute to better use of the existing infrastructure.

The article deals with topical issues of development of the market of tank-container freight transportation in Russia. The study presents data on the use of tank-containers on various modes of transport, which allow high-quality and reliable transportation of goods in comparison with traditional tanks. The technological features of the design of tank-containers, their overall dimensions, weight and capacity are considered. Statistical information reflecting the dynamics of the chemical cargo transportation market in containers and tanks has been analyzed. The risks and threats that can lead to an environmental disaster due to the problems of updating the fleet of containers have been studied. The directions of development of smart logistics are given.

Train trip package transportation is an advanced form of railway freight transportation, realized by a specialized train which has fixed stations, fixed time, and fixed path. Train trip package transportation has lots of advantages, such as large volume, long distance, high speed, simple forms of organization, and high margin, so it has become the main way of railway freight transportation. This paper firstly analyzes the related factors of train trip package transportation from its organizational forms and characteristics. Then an optimization model for train trip package transportation is established to provide optimum operation schemes. The proposed model is solved by the genetic algorithm. At last, the paper tests the model on the basis of the data of 8 regions. The results show that the proposed method is feasible for solving operation scheme issues of train trip package.
