Abstract
This paper shows a method to predict aerodynamic loads on track side objects, like spheres or discs, induced by the head pressure wave of a passing train. The loads are calculated using potential flow theory. The results are compared with experimental data which were measured in a moving model rig using three different train geometries. It is shown that the loads on a sphere can adequately be predicted, while it is still unclear which physical effects are important at all for the loads on a disc. The interaction between the flow field around the train and a track side object seems mainly to be driven by linear unsteady effects. Further, the loads depend strongly on the used train head geometry.
