Abstract
Moving model experiments are used to investigate the flow around three different train geometries. Due to the difference in the Reynolds number, the flow might not be directly comparable to full-scale measurements. Boundary layer control is used to influence the flow around the train model and increase the boundary layer velocity. With view on the standards given by the Technical specification of Interoperability, the analysis of the wake shows increased maximum induced flow velocities at the specific standard measurement position.
