This quantity includes the contributions to the 9th foreign Workshop on Railway Noise, held Sept 04-08, 2007, in Munich, Germany. The workshop featured lectures by means of foreign leaders within the box of railway noise and vibration.
All topics with regards to railway noise as noise assets (rolling noise, aerodynamic noise, bridge noise, sonic boom), prediction instruments and theoretical types, new noise aid, expertise in addition to ground-borne vibration are tackled.

This paper concentrates on the analysis of track as well as free field vibrations for different train speeds at a site along the line L2 between Brussels and K¨oln. At this site, 11 passages of the IC train at speeds between 156 km/h and 225 km/h have been recorded and 11 passages of the Thalys HST at speeds between 218 km/h and 326 km/h. The experimental data for different train speeds are analysed and compared to numerical predictions that have been performed by means of a numerical model that accounts for the dynamic interaction between the train, the track and the soil.
The model accounts for the dynamic interaction between the train, the track and the soil by means of a compliance formulation in the moving frame of reference. The results of track as well as free field vibrations during the passage of an IC and Thalys train are used to validate the model. The quasi-static contribution is used to calculate the track response, while only the dynamic contribution is taken into account for The Influence of the Train Speed on Vibrations Due to High Speed Trains 25 the free field response.
The influence of the primary suspension is small at frequencies higher than 10 Hz, so that each axle can be represented by its unsprung mass Mu (tables 1 and 2). Figures 3 and 4 compare the measured and computed frequency content and time history of the vertical free field velocity at 8 m and 48 m from the track, during the passage of the IC train at a speed of 224 km/h and a Thalys HST at a speed of 218 km/h and 307 km/h. The frequency content is mainly situated in a range upto 100 Hz (figure 3), with a shift towards lower frequencies for an increasing distance from the track (figure 4).
