Justification of the Difficulty of the Path Profile of the Markand – Kattakurgan Section with Diesel Traction

Abstract

This article examines the issue of the effectiveness of using diesel-powered mainline (train) locomotives on real sections of the Uzbek railways of varying difficulty. The authors adopted an evaluation criterion and substantiated the parameters of the difficulty of the track profile of a hilly-mountainous section of the railway with diesel traction, which are the basic components of the energy efficiency indicators of locomotives. The most difficult stretch of the studied hilly-mountainous section of the Uzbek railway is justified. The results of the study obtained by the authors are recommended to specialists of the locomotive complex of railways for rationing and forecasting the consumption of natural diesel fuel for train traction, consumed by diesel locomotives, as well as for assessing the difficulty of the track profile of the railway line (direction) Samarkand - Navoi - Bukhara of «Uzbekistan temir yo'llari» JSC.
