Justification of the Efficiency of 3vl80s Electric Locomotives on the Markand – Navoi Section of the Uzbek Railway

Abstract

The results of substantiating the parameters of the transportation operation of three-section mainline (train) freight electric locomotives 3VL80S on a real hilly-mountainous section of the railway when moving freight trains with stops at intermediate separate points, as well as assessing the traction quality of the track profile of the hauls of this section are presented. The criterion for the mentioned assessment is the given values of the total and specific consumption of electrical energy for traction of trains in quantitative and monetary terms, taking into account the values of the reduced running time of the train in traction mode and the specific consumption of electrical energy per trip that accompany the transportation process. The research results were obtained using methods and techniques of the theory of locomotive traction, taking into account the average values of the main indicators of traction and energy efficiency of using the studied 3VL80S electric locomotives in the form of tabular data and graphical dependencies, as well as practical conclusions and recommendations.
