    This paper focuses on analyzing the driving characteristics of railway vehicles on selected tracks. The aim is to compare the vehicle's driving parameters when changing the propulsion system. The introductory part of the article discusses the transition from diesel to hydrogen propulsion, including a mention of modern vehicles using this type of propulsion. Furthermore, a specific railway vehicle with the potential for conversion to hydrogen propulsion is introduced. The main part of the article deals with the computational analysis, encompassing the characteristics of the necessary input parameters of the current propulsion system and the results of the vehicle's driving analysis. Subsequently, the vehicle's parameters were defined after the conversion to hydrogen propulsion, and an analysis was performed with these new parameters. The main goal was to compare the parameters of the current propulsion system with those of hydrogen propulsion on selected tracks.
