In conventional railways, when utilizing concentrated power, the train configuration is determined based on the locomotive's power and the types of cars used in the train. The total train mass must first be defined for a given limiting gradient. Based on the total train mass and the load and tare weight of the cars, the specific train composition (the number of cars) is determined. For urban rail and high-speed trains, which primarily serve passenger transportation, a different approach is required, particularly for distributed-power trains. In such cases, basic resistance is not calculated separately for each car but for the entire train. The number of cars is typically structured into fixed modules, requiring an assessment of how many motor cars should be included within a given train configuration. To address this issue, the article presents the basis for selecting the configuration of high-speed trains with distributed traction. Based on this, configurations for several different options were selected, and the feasibility of utilizing kinetic energy to overcome limiting gradients along the line was also verified
