Summary

This paper gives an overview on different experimental methods for the measurement of the aerodynamic drag of railroad vehicles in general as well as on the measurement of drag of submerged bodies in water in particular. It is shown that water based drag measurements with moving railroad models are very promising in terms of overcoming disadvantages in wind tunnel testing with scaled models. For this reason, a test setup in the water towing tank of the Technical University of Berlin is being developed to adapt the physical boundary conditions including high Reynolds numbers for more accurate results and the possibility to investigate full length model train compositions. Advantages and limitations of these experiments in water are discussed and preliminary results are presented.
