Increase in speeds of high-speed trains is generally accompanied by increased levels of generated ground vibrations. Especially large increase in ground vibration amplitudes occurs for trans-Rayleigh trains, i.e. for trains travelling at speeds larger than Rayleigh wave velocity in the ground. Calculations performed for French TGV or Eurostar trains show that the averaged increase about 70 dB takes place as compared with conventional trains. Effect of track bending waves may cause noticeable reduction in amplitudes of ground vibrations generated by trans-Rayleigh trains if the train speeds approach the minimal phase velocity of track waves.
