The vibrations of the permanent way elements from the shock pulse have been analyzed. It has been shown that the ability of the applied type of straple to damp high-frequency vibrations could be judged on the nature of the permanent way elements oscillation vibrogram. It has been proved that the analytical conclusions on the nature of vibrations of each tested permanent way element could be made on the basis of statistical analysis of the experimental data.
