The article is devoted to the study of energy-efficient use of traction rolling stock for driving trains. It deals with the optimal driving mode and the main parameters of traction calculations. Based on the use of GPS/GLONASS satellite navigation units, a method for determining the basic resistance of cars in real time is proposed. The possibility of using the results obtained on locomotives with analog devices and no movement tracking is analyzed. The “Traction Calculations” software package in the C# programming language was modified in order to reduce the time and facilitate calculations of the locomotive traction service. In the course of the study, the equation of the main resistance of the cars of train No. 3612 was determined. On the basis of the uncoupled rolling stock, the dependences of speed, time, heating and current of traction electric motors, fuel consumption by the CHME3 locomotive of the Kharkiv-Sortirovochny locomotive depot for the transportation of cars from the Kharkiv-Sortirovochny station to Merefa station were calculated, with recommendations for the driver to use the position of the driver’s controller in order to reduce costs and fulfill the train schedule.
The article considers the issues of determining rational approaches to the creation of train maps, the rational use of diesel modes and the use of automated computer simulation system. Based on the obtained results, an energy-efficient mode of train driving is proposed and a mathematical model of the locomotive operation character is created. There is a need to review obsolete regime and train locomotive crews in the latest methods of operation. The basic values and methods of calculation for specific operating conditions on the basis of the law of conservation of mechanical energy are established. It is proposed to create a passport of each locomotive to determine the rational weight norms on the existing service shoulders. After all, overloading or underutilization of the locomotive's resource is associated with loss of profit or the emergence of emergencies. The necessity of the offered methods within the limits of ecological requirements to traction rolling stock is proved. The possibility of forming a rational system of mileage between technical inspections and repairs for each locomotive as a whole on the basis of forecasting and statistics is determined. It is recommended to further implement mathematical modeling and digital means of monitoring the technical condition after repairs to achieve economic efficiency of railway transport.

The article deals with the issues of environmental taxation of carbon dioxide emissions by the countries of the European Union and the methodology for calculating the amount of emissions by regulatory documents of Ukraine. It is established that our country's methodology is not adapted to real operating conditions under the influence of cross-border carbon taxation and the "Emissions Trading System". A mathematical model of the impact of power generating stations of states and their contribution to the overall energy balance of the country on the environmental cost and mass emissions of 1 kWh of electricity generation is proposed. The amount of electricity losses during its transportation from the power plant to the electric moving warehouse is determined and is taken into account in the total amount of deductions for the "Emissions Trading System" for DC and AC railway networks. Schemes of transit and local cargo routes are considered on the basis of a real fleet of traction rolling stock of Railways and a network of logistics lines. The passport characteristics of locomotives are analyzed and the amount of emissions and deductions during operation at Rated mode and idle speed is determined. Specific norms for selected routes and train conditions are calculated. The total costs, their cost and the amount of emissions and taxation of selected routes are determined, and rational economic and environmental logistics lines of train traffic are determined on their basis.
