The study presents a selection of vibration measurement results in the ground surface layer. Pendolino, InterCity trains and cargo train caused free-field vibrations. Runs at variable speed on two trackswere analyzed to have comparison. Vibration measurements were realized during the certification test of newly purchased Pendolino train. In the paper vibration acceleration records obtained in time domain and frequency domain (FFT) and their dependence on the position of the accelerometer are presented. The acceleration of vibrations in the individual sections shows a great backdrop of the propertyvibration especially between sensors located closest to the centre of the track. The paper also presents the results in the time – frequency domain using short-term ourier transform (STFT) for comparing the nature of the obtained excitation vibration which depends on rolling stock, track and speed at which the train was running. The results show that the change of rolling stock previously operated on Pendolino will reduce vibrations in the surrounding of railway lines.
