The author introduces the results of rationale for the transportation work parameters of three-section mainline (train) freight electric locomotives on a real Uzbek railway section with non-stop and stop-and-go freight traffic at passing tracks, intermediate stations and intersections, as well as estimation of the traction qualities and properties of the track profile in this area. The criteria for the estimation are adjusted values of overall and specific electrical energy consumption for traction power in the terms of quantity and money as well as accompanying values of adjusted time taken in traction mode and the specific electrical energy consumption for the trip. The research results were received as tabular dates and graphic arts dependences with the use of methods and techniques of locomotive traction theory and the main parameters of traction-energy efficiency of the considered electric locomotives.

The research results are recommended for practical application by engine-drivers-instructors and thermotechnics engineers as well as by other specialists of line enterprises of the locomotive complex of Uzbek railways with professional and productive activities concerning with the issues of energetics of moving the freight and passenger trains on real or virtual railway sections.
