Full scale laboratory experiments on the dynamic behavior of a railway track and its constituents with respect to the coupling conditions to the ground are performed. Their effects on the frequency response functions of the track lead to special investigations on the wave propagation in the subsoil and the dynamic displacement fields of the rails and the sleepers by use of the holographic interfereometry. Moreover, wave propagation through the soil is observed when various inhomogenities are placed into the ground in order to isolate neighbouring constructions.
