Abstrakt EN: The actual problems solved for Czech Railways by Railway Research Institute are described in this paper. It deals with an evaluation of the interference influence of the electrical engines, which came into the foreground of interest again with coming of the modern engines of the fourth generation. These interference influences adversely affects the other railway equipment, above all the communication, signalling and interlocking devices, what can negatively affect fluency and safety of the railway transport. A substantial feature of innovation is a change from the original analog processing of the measured signal to the digital one. The aim of this signal analysis is the amplitude determination of all the important spectral components, including their time dislocation and duration time. The solution consists in obtaining a time-frequency point of view on signal for whose acquisition STFT and CWT methods were selected. The program Matlab was selected as an executive instrument for these analyses.
