The paper presents principle of track/bridge interaction in the case of temperature gradient, breaking and acceleration of railway vehicles. Influence of different bridge structures to the bridge expansion length was analysed for the purpose of expansion joint avoiding in CWR track. This would lead to the reduction of noise and vibration emission from railway traffic and maintenance activities, which is especially important in the urban environment. Additional stresses in track were considered according to the type of track and bridge deck, type of bridge bearings, as well as bridge support stiffness. Conclusion of this paper provides basic stances that could be used for the calculation of different railway bridge structures. The aim of the paper is providing the basis for improvement of the existing technical regulations in the field of railway infrastructure, as well as its harmonisation with EU regulations.
