The subject of the article is the analysis of ride comfort for a passenger of selected types of rail vehicles on the basis of the main factor determining its level - mechanical vibrations. The research was based on measurements of vibration accelerations and the RMS values in one-third octave bands which were calculated from the measured accelerations. The tested objects were four types of rail vehicles. This article presents the results of the analysis carried out for each vehicle, using two
