About the Difficulty of the Path Profile of the Marokand – Kattakurgan Section of the Uzbek Railway

Abstract

This article relates to research into the effectiveness of using mainline (train) locomotives of diesel traction on sections of the Uzbek railways of varying complexity. The obtained values of the criterion for assessing traction quality and the properties of the track profile made it possible to select the most difficult section of the studied hilly-mountainous section of the Uzbek railway with diesel traction for traffic conditions without stops at intermediate stations. The results of the study are recommended to specialists of the locomotive complex to substantiate the consumption standards of natural diesel fuel for traction of trains and to assess the difficulty of crossing the profile of the track and route of the railway line (direction) Samarkand - Navoi - Bukhara.
