Purpose. Traction calculations with the definition of energy-efficient trajectories provide search for rational energy consumption depending on the time course of the train. When selecting energy-efficient trajectory of the train and the development of regime charts conducting trains must take into account variables such as: the profile of the site, weight train, locomotive series, etc. When increasing the speed of the growth it occurs the resistance movement, which is proportional to the square of the speed, which leads to higher costs of fuel and energy resources. In contrast, the reduction of costs due to the decrease in speed leads to an increase in travel time of the train, which should be consistent with the timetable and other technical and economic parameters, depending on the speed. The article describes one way to reduce the cost of energy for traction. The aim of the article is to reduce energy consumption by identifying energy-saving control modes. It occurs with the locomotive optimization function of control actions on the running time of the train and the flow of energy in the management of the train from the end of the acceleration to go to the coasts. Methodology. The technique of choice of energy saving path of the train and power control and electric locomotives with electric transmission provides the calculation of multiple paths with variable input data and parameters of the composition of the train situation. The methodology takes into account the uniform mathematical methods of search and parametric optimization. For uniformity of motion needed to slow down the accelerating forces are balanced. Findings. On the basis of calculations of multiple advanced algorithms determine the trajectories of energy-saving trains, built multiparametric locomotive power control function, which can reduce energy consumption by 11 to 13% depending on the weight of the train and the train situation. Originality. The author obtained the energy-saving function of traction control of locomotive for the corresponding uniform velocity, which depends on the weight of the train and bias. Practical value. In contrast to existing development of rational management of trains, this function requires much less computing time with a high accuracy of calculations. It allows using the algorithms in the onboard control systems, locomotive and energy savings.
