Currently, much attention is paid to the creation of terminal «dry port» for maintenance of traffic node. «Dry port» is one of the possible ways to increase capacity of the transport node. The capacity of transport node depends on the following interrelated elements: infrastructure solutions, technological, technical, organizational, and exogenous. Insufficiency of technical equipment, low level of production culture, informational inconsistency - lead to excessive downtime of vehicles at berths and terminal and warehouse facilities of the port. Technical devices, shunting locomotives, lifting and transport equipment cannot cope with the increasing flow of transportation of containers and cargo, leading to paralysis of the movement of freight flows. The result is the accumulation of cars at the entrances to the transportation hub the formation of «abandoned» trains. The lack of logistics management principles of traffic promotion in the organization of multimodal transport required a modern approach to organization of effective work of the transport node. In this work the effective interaction between various types of transport in the transport node is represented in the form of a set-theoretic model. Considered the elements that contribute to the throughput of dry ports and sea port. The efficiency of technological processes systems of interaction of railway and marine transport in the node depends on the following conditions: the actual time of wagons in transportation must comply with regulatory process time; organization supply wagons in accordance with the processing capabilities of the cargo platforms; ensuring the maximum amount of overload of goods on the «direct option». To implement these conditions it is necessary to organize the interaction of different modes of transport in the transport node together with the terminal «dry port» in the system «terminal - station - port», in which the capacity of the railway component of the transport node is treated comprehensively along with the «dry port». Further technical and technological development of transport nodes is organization of cargo handling outside the port terminal «dry port».

Today the most part of world commodity and cash flows is concentrated in the Pacific Rim. The strategy of development for the Far East is based on increase in export to Asia-Pacific countries and also growth of volume of foreign investments. In September, 2018 in Vladivostok at the IV East economic forum the VaninoTransUgol company will submit the construction project in seaport Vanino of transport transshipment facility with transshipment capacities to 40 million tons. In 2017 the volume of transfer of freights in Vanino port was 7,2 million tons, the seaport continues to increase the refinery capacities, but the insufficient capacity of infrastructure of railway transport is the limiting element of development of the transport hub. Construction of the new terminal for transfer of coal will demand corresponding development of railway infrastructure of the Vanino transport hub. In the conditions of increase in volumes of transfer of freights, it is necessary to resolve an issue of the extreme number of cars which can be processed in "the railway station-seaport" system. The author has developed the program of imitating modeling which allows to determine the capacity of a railway component of the transport hub at the existing hardware and in the conditions of increase in loading of "the station-the port" system. In this work results of imitating modeling of work of the Vanino transport hub at increase in unloading of coal by 40% up to 280 cars a day are presented. The working park of the Vanino station has made 305 cars and continued to increase, ways of the station have been filled with cars waiting for operations. Two groups of possible ways of increase in capacity of the transport hub - infrastructure and technology solutions are presented. In the conditions of limitation of territorial development, construction of additional railway infrastructure becomes impossible therefore it is possible to increase the capacity of the transport hub due to change of specialization of moorings of port. It will allow to reduce the number of the cars which are on the ways of the station waiting for unloading and to accelerate processing of the rolling stock. After re-equipment of moorings of port, the working park of the Vanino station has made 230 cars and the capacity reserve for reception of an additional traffic volume has appeared. By means of this program of imitating modeling it is necessary to analyse work of key transport hubs of the Far East for definition of the maximum traffic volume at which transport hubs will steadily function, in the optimum mode.
