Rail dampers are mechanical devices mounted at both sides of the rail web aiming to reduce the vibration along the rail. In this way, a shorter length of the rail vibrates effectively and the rolling noise is less intense. In this paper, a continuous model consisting in an infinite Timoshenko beam on multi-elastic layers is adopted for the railway track with rail dampers. The equations of motion are solved using the Green's function method and the frequency-response of UIC 49 rail is derived and analysed in terms of the receptance and decay rate of vibration depending on the possible dimensions of the rail dampers.
