The results of the calculation of the kinematic parameters of the movement of a freight train by a graphical method on a virtual hilly section of a high-speed railway when moving without stops and with stops at an intermediate and final station are presented. The values of energy efficiency indicators of UzTE16M3 diesel locomotives were obtained in quantitative and monetary terms when driving a freight train of a unified mass of train. The research results are presented in the form of tabular data and will be implemented by specialists of the locomotive complex in substantiating the efficiency of the transportation work of UzTE16M3 diesel locomotives in real operating conditions.

“…The specified diesel locomotive refers to a land-based wheeled vehicle with a power energy plant [3] -this is diesel 1A-5D49 of the third version, which is characterized by high efficiency with specific fuel consumption at rated power mode (2206 kW) equal to 208 g/kW-h and hourly fuel consumption of idle mode -14 kg/h. An analysis of scientific research by domestic scientists [4][5][6][7][8][9][10][11] and scientists from far abroad [12][13][14][15][16][17][18][19][20][21][22][23][24], aimed at studying the efficiency of various types of locomotives, their systems, units and apparatus in the conditions of operational activity of railways and of railway transportation of goods the organization, indicates that no the a sufficient degree of study of issues related to the justification of the kinematic parameters of the movement of freight trains and the parameters of the energy efficiency of locomotives on virtual and real sections of railways of varying complexity, including of Uzbek ones.…”

A program algorithm and a method for producing (performing) traction calculations are proposed, based on geometric constructions of changes in the speed and time of train movement along the track, relying on the specific resultant forces of the train in the travel track of rolling stock. Calculations of the kinematic parameters of the movement of a freight train on a virtual hilly section of the railway were carried out using a graphic-analytical method when moving with stops and without stops at the intermediate and final stations. The values of the energy efficiency indicators of UzTE16M3 diesel locomotives when driving a freight train with a minimum train weight in quantitative and monetary terms are substantiated. The numerical results of the research are obtained in the form of tabular data, which specialists of the locomotive complex can use when analyzing and assessing the efficiency of the transportation work of UzTE16M3 diesel locomotives under real operating conditions.

“…In the field of train operations, a series of scientific works have been carried out to optimize the movement of trains based on the calculations made by our country's scientists [8][9][10][11][12][13][14][15][16]. However, in the process of implementing these optimization calculations, the basic principle of considering all types of wagons when calculating the resistance to movement has not been taken into account.…”

The primary specific resistance to the movement of freight wagons is a key parameter for normalizing the time and energy consumption of trains. Although the “Rules of Traction Calculations” calls for dividing wagons into six groups when calculating this resistance, in practice (using the traditional method), appropriate regulations are developed based on the separation of train wagons into two groups (4th and 8th lips). One of the main reasons for this is the inability to account for the unique features of each wagon in a given train. To address this issue, a program was developed for determining the necessary parameters of wagons for traction calculations based on their identification numbers. This software can be accessed through the website https://trainlocomotive.netlife.app/. Using this program, a method for calculating the primary specific resistance to the movement of freight wagons has been developed. Field sheets of freight trains moving through the Uzbekistan Temir Yullari railway station were analyzed. As a result, it was discovered that nearly half of the freight train composition consists of empty wagons, while the proportion of loaded gondola cars and tanks is 23%. The primary specific resistance to the movement of wagons in such a mixed composition is calculated using both traditional and developed methods. The impact of the primary specific resistance on the energy costs of maintaining the train is evaluated. As a result, the feasibility of utilizing the developed method for normalizing electricity consumption based on traction calculations is demonstrated.
