One of the priority areas of economic development of the Far East Region is focused on the communications with the countries of the Asia-Pacific Region. The region is crossed by the largest railways, such as Trans-Sib and Baikal-Amur, which have an access to the Far East seaports that promotes the growth of international trade operations and the increase of the transit traffic in the region. An expansion of transport and economic relations of our country in the Far East Region, the implementation of a considerable number of extractive industry programs ​​ within Baikal-Amur Region, the development of the sea ports of the Far East Region will cause the growth of the workload on the rail infrastructure that is impossible without its development and modernization.

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».

This article is devoted to the investigation of the internal parameters of transformers used for power supply of railway automatic and telemechanic devices. In this paper, the change in the nomogram of the impedance area of a power transformer is considered when changing the parameters of the replacement circuit of this transformer. The possibility of visualizing the change in the parameters of a transformer using the mathematical apparatus of conformal mappings is shown. The nomograms of the input resistance of the single-phase oil transformer are constructed with a change in the value of the insulation resistance and the transient resistance at the junction points. Based on the constructed nomograms, conclusions were drawn on the behavior of the input impedance region of the transformer in various situations.
