The paper is devoted dynamic effects in the track structure - the quasi - static excitation due to moving load, as the important source for the response of track components in the low frequency area (0 Hz less than f less than 40 Hz). The low-frequency track (the rail) response is associated with periodicity of wheel sets, bogies, and carriages of passage trains, The periodicity of track loading is determined by so called dominant frequencies f(d) at a position x of the track.
