Methodology for Assessing the Efficiency of Using Diesel Locomotives on Railways Sections

Abstract

A methodology is presented for substantiating the operational efficiency of the transportation work of locomotives, based on the data of route sheets and speed measurement tapes of the locomotive driver. Analytical expressions are proposed for the developed algorithm for the numerical study of mechanical work and diesel fuel consumption of diesel locomotives, and the calculation of their components (commands) using a computer hardware and software complex for a separate trip according to the route sheets of driver of the diesel locomotive. The results of processing speed measurement tapes and route sheets of diesel locomotive drivers on some real sections of the Uzbek railway are obtained in the form of tabular data, the analysis of which indicates that the most accurate and complete indicator characterizing the current energy state of locomotives of diesel traction will be the efficiency of the power circuit η of diesel locomotives.
