The article provides a rationale for the kinematic parameters of the movement of freight trains with masses different and the energy efficiency parameters of 3VL80S electric locomotives on a virtual hilly section of the railway. In order to implement this justification, a method of graphically integrating the differential equation of train motion is used, which is the basis of the algorithm for performing traction calculations for the movement of the freight trains under study without stoppings at an intermediate station. Kinematic parameters of the movement of freight trains and energy efficiency indicators of 3VL80S electric locomotives are obtained in the form of tabular data and regression equations according to their definition on railway sections with the second type of track profile, which can be used in predicting and normalizing the consumption of electrical energy for traction of trains. The research results are recommended for implementation into work by specialists of the locomotive depots operation workshop of «Uzbekistan Temir Yollari» JSC.
