The known approaches to the classification of factors affecting the energy consumption of the train are considered, and their main disadvantages are identified. The validity of existing classification methods and the completeness of accounting for factors affecting energy consumption are evaluated. It is shown that none of the known approaches to classification gives a complete picture of all the influencing factors and the degree of their influence on the energy consumption of the train, since it does not fully take into account the physical nature of the individual components and the overall power consumption for traction. Based on the analysis of the energy balance of the train articulated principles and criteria for the classification of factors influencing energy consumption, considers the interconversion of different forms of energy and describe their energy diagrams in the different modes of the train movement. The analysis made it possible to identify the factors that affect the power consumption of the train in all modes of movement, and evaluate them according to various criteria. A classification of factors affecting the train's electricity consumption is proposed, which allows us to justify the correct method of accounting for each factor, develop measures to reduce the influence of individual factors on energy consumption, improve the system of analysis, rationing and forecasting of electricity consumption for train traction, and competently solve other problems of electric traction energy.

The most important task of the Russian Federation's energy strategy is the efficient use of energy resources. Rail transport is a one of the major consumers of diesel fuel and electricity, where the major energy consumption is used for traction. Traction energy consumption depends on a number of operational factors, including the characteristics of high-speed trains. The article is devoted to the designation of ways to assess the impact of changes in the coefficient of the precinct speed of freight trains on the change in specific energy consumption of locomotives. It is concluded that the calculation influence coefficient use indicators of locomotives, including the coefficient of the precinct speed must be performed for each of the structural units and analyzed the calendar period. Proposed by the authors for this formula is included in the methods of analysis and forecasting of energy resources consumption for traction trains introduced on the Russian train system in 2015.
