Dynamic behaviour of railway track subjected to moving vehicles is affected by random deviations of its parameters from their nominal values. The most important factor of stochastic character is the rigidity of the substructure which is correlated with the random track irregularities. The first approximation of the load which is moving along the longitudinal axis of a beam (rail) may be represented by a lumped mass or by a system whose transfer functions are known.
