The article presents the results of investigation of intermediate rail faste nings influence on vibrodynamic impact transferred to roadbed soils.Comparative analysis of oscillations in different types of fastenings revealed varying efficiency level of TB (terminal bolted) and ARF (anchor rail fastening).At the section, having ARF fastenings, dependencies standing for the change of an amplitude value at the increase of passenger train speed, are a straight line; whereas at the sections with TB fastenings dependencies for passenger trains travelling at a speed exceeding 160Â km/h cease to be straight.The change of the level of vibrodynamic impact transferred to the roadbed soil result from both design features of fastenings and changing stiffness of shock absorbing cushions.
