Summary
This paper describes the work carried out as part of Work Package 2 of the TRANSAERO project to produce an extensive and well-documented database about pressures generated by train passing at high speed in open air and in tunnels. Tests have been carried out on Italian high speed line using two Etr 500 trains and a freight train. Pressures signals, which have been measured on several locations along the Etr 500 and the freight train, are available for a large number of train speeds both in open air and in tunnel. The main test results are presented in the paper. As far as the open air tests are concerned, the pressure distribution along a train section is analysed and the pressure values measured at different speeds are compared. As regards tunnel measurements, the analysis of pressure distribution and the influence of train speed is presented not only in the phase of train passing, but in the complete time history in tunnel in order to compare the effects of train passing with the effects of pressure waves.
