Ground vibrations generated by the operation of high-speed trains are one of the significant challenges at hand. These vibrations have the potential to cause harm to nearby structures through horizontal and vertical ground accelerations. A combination of sand crumb rubber (SCR) mixture and geofoam is explored as a vibration screening barrier parallel to the railway track. In the present study, train speeds of 80, 160, and 300 kmph were considered. A four-story building with a concrete frame structure near the railway track was simulated. Several parametric studies were conducted in this investigation. The variation in building acceleration at different floor levels caused by ground shaking from train-generated vibration was computed for various screening materials. There was an 8–10 dB vibration reduction after the trench, meaning that in areas with an excessive number of buildings, a combination of SCR and geofoam barriers might be placed parallel to the rail track.
