A method to an assessment of influence on the expenditure of electrical energy for traction of trains, parameters of graphic time-table in the conditions of using the regenerative braking is being considered in the article. The retrieval of version with the minimal using of energy is based on the modeling of graphic time-table by different train-to-train intervals in the conditions of burst-mode access’ organization on the railway section. By results of modeling it is proposed to represent the derived dependence by changing of electrical energy’s expenditure on parameters of graphic time-table in the form of analytic function of several variables n-order forthe following using by normative plotting of movement for the purpose of curtailing electrical energy’s expenditure for traction on the trains.

In this article, a scientific approach to optimizing the electromechanical route for servicing the centralization and blocking devices at the station is considered. For this purpose, the authors propose to use the algorithm for solving the known traveling salesman problem. This algorithm is the basis for constructing technological maps of the movement of electromechanics around the station, as a component of technological maintenance cards for automation and telemechanics devices.
