The article presents the results of substantiation of the transportation work parameters of three-section mainline (train) freight electric locomotives 3VL80S at the real hilly-mountainous railway section, when the freight train moves non-stop and with stops at intermediate stations, passing loops and operation points, as well as the estimation of the tractive performance (properties) of the track profile of the hauls of this section. As a criterion of the afore-mentioned estimation, the given values of general and specific electric energy consumption for train traction in quantitative and monetary terms are proposed, taking into account the values of the train travel time in traction mode and specific electric energy consumption per trip, accompanying the transportation process. The results of the research were obtained using the methods and approaches of the theory of locomotive traction, taking into account the averaged values of the main indicators of the tractive and power efficiency of the utilization of the investigated electric locomotives 3VL80S in the form of tabular data, graphic dependencies and practical conclusions. The results of the research are recommended for practical use to locomotive drivers engine drivers, heat engineering instructors and specialists of linear enterprises of the locomotive complex of the Uzbek railway network, whose professional and production activities concern the issues of energy of the freight and passenger trains movement at the real the hilly-mountainous sections and virtual railway sections that are identical to them.
