The article considers technology of the unified control of the transportation process at the eastern operation area of the JSC “Russian Railways” network, which includes four railways: Krasnoyarsk, East Siberian, Transbaikal and Far East. This organization of operational work is a pilot project to create a polygon management in general on the network. It is shown that at the eastern area in the most concentrated form various operational tasks are solved in a unified coordination of the structural enterprises of the production and marketing units of JSC “Russian Railways” on all four railways. There are only two external junctions with other railways, the lines are electrified only by alternating current, the origin and downturn of freight flows occurs mainly within the area. The governing body of the polygon - the TCC EP (TsUP VP) was given the authority to provide regulatory support for the transportation process and to manage the operational work, the implementation of which was previously envisaged at the central and road levels. Authors show the polygon technology of the TCC EP work in the area of the traffic schedule and the train formation plan, the order of rationing and provision of "occupatios" for repair and construction works, logistical support of transportation, operational management of the transportation process, information support and evaluation of the activities of the TCC EP. The structure of management is presented. The developed technological process of the TCC EP operation should become the basis for solving practical problems in the field of the implementation of the polygon control technology for the transportation process, both at the eastern range and at other sites of the JSC ”Russian Railways” network.
