“…An analysis of scientific research by foreign scientists [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], carried out by the author of this article, indicates that these works do not consider the issues of energy efficiency of locomotives of electric traction in real conditions of organizing freight traffic on sections of Uzbek railways and do not use methods of traction theory trains.…”

The results of the substantiation of the average kinematic parameters of the movement of freight trains and the energy efficiency indicators of the transportation work of locomotives of electric traction without stops and with stops on a virtual hilly section of the railway are presented. The stated goal of the research was realized through the theory of locomotive traction through a graphical method of integrating the differential equation of train motion, based on the finite increment method, with subsequent calculation of the numerical values of the specified parameters and indicators. Research results obtained in the form of tabular data, graphical dependencies and equations regression to determine the efficiency indicators of locomotives of electric traction on virtual and real hilly sections of railway, which are recommended on the practice work of specialists in the operation workshop of locomotive depots of the Uzbek railways.

“…The analysis of scientific research by scientists of the far abroad [3][4][5][6][7][8][9][10][11][12][13][14][15], conducted by the author [16,17] for traction diesel and electric rolling stock, including high-speed, testifies that in modern theoretical research only a few of them consider questions of realization of the practical component directed on increase of efficiency of use of locomotives. Indeed, only the works [6,7,15] substantiate and recommend various technical and design-technological solutions to ensure the possibility of reducing the consumption of fuel and energy resources for the movement of freight trains, primarily by diesel and hybrid traction locomotives, to the practice of linear enterprises of the railroad network.…”

The paper presents the results of research on the justification of parameters of transport operation of three-section main (train) UzTE16M3 freight diesel locomotives on the high-speed railway section Marokand- Kattakurgan of JSC “Uzbekistan Temir Yullari” when moving freight trains without stops and with stops at intermediate stations, passing points, and separate points. The specified results were obtained by methods of locomotive traction theory in the form of tabular data, graphical dependences, and regression equations for determining logistical kinematic parameters of freight train traffic and the main energy efficiency indicators of the investigated diesel locomotives in a given section. The research results obtained by the authors can be used by drivers - instructors in thermal engineering and specialists of linear enterprises of JSC “Uzbekistan Temir Yullari” locomotive complex, whose professional and production activity is connected with the issues of saving of natural diesel fuel consumption by diesel locomotives on high-speed sections of the railroads.

The results of a theoretical study evaluating the effectiveness of using Uzbek diesel locomotives of the UzTE16M3 series during the non-stop movement of freight trains on the hilly-mountainous high-speed section Marokand - Kattakurgan of the Uzbek railway are presented. The reference point for the implementation of this assessment was the mathematical model of the movement of a freight train developed by the authors and the algorithm for performing traction calculations, which are prerequisites for substantiating the numerical values of the parameters of the logistic indicators for the process of railway transportations of goods in real conditions of the organization of operation. The authors obtained the parameters of logistics indicators in the form of numerical tabular values and graphical dependencies, and the corresponding regression equations were proposed to calculate the indicators of transport logistics. The data obtained by the authors can be used by specialists of the locomotive depots “O’zbekiston temir yo’llari” JSC, whose production activities are related to the issues of forecasting and normalizing the consumption of full-scale diesel fuel by diesel locomotives on the hilly-mountainous, of hi high-speed sections of the Uzbek railways.
