The vertical track dynamic model is described in the paper as a periodic structure. It is composed of rails modelled as Timoshenko or Bernoulli-Euler beams, sleepers (lumped masses) and pads and ballast modelled as viscoelastic elements. Particular attention is paid to the influence of pad characteristics on the dynamic stiffness of the track. One of the ideas of the new pad generation is also presented in the paper. Some parameters of the pad are given.
