note = {Wave propagation in an infinite periodic railway track is investigated. In the analysis the constituents of a rail and sleepers are considered for the track model. Propagation modes of the periodic structure are described by virtue of the Floquet transform. This method makes it possible to reduce the infinite periodic problem to an eigenvalue problem for a unit structure with finite length. The rail is modeled by a Timoshenko beam and discretized by finite elements. Through numerical analysis the wave number-frequency curves for the propagation modes are obtained. It is found that the installation of sleepers causes a mode in which the propagation waves are accompanied by sleeper vibration. Besides, the influence of the stiffness of rubber pads on the propagation modes is discussed.},
