Aerodynamics of high-speed railway systems and maglev systems do not differ in terms of physical principles and analysis methods. However, there might be substantial differences in terms of system layout which also lead to different focuses in the field of aerodynamics. From the system perspective a proper design of a maglev system with single-track tunnels involves a balanced and optimized compromise between general and superior requirements - in this case especially the limitation of required tunnel cross section due to various reasons and the various (competing) technical requirements, namely - the limitation of train-induced aerodynamic loads acting on the train and on the infrastructure, the affirmation of an appropriate pressure comfort to passengers, - the global avoidance of bothering micro-pressure wave emissions, - the limitation of aerodynamic resistance. For the Munich maglev project, corresponding studies had been carried out and system parameters had been decided. Now, it has to be ensured that deduced train specifications, especially regarding pressure tightness, its interrelation with the HVAC system and the actual aerodynamic resistance of the train seem will be matched. With respect to the topic of micro-pressure waves, the experiences recently made at the Nuremberg-Ingolstadt line need to be accounted for. Within the framework of further development of the German maglev system and against the background of projected increase of tunnel speeds it is recommended to intensify / to initiate - studies on perceived pressure comfort and on a active system to control the train's inner pressure. It should be mentioned and appreciated, that also high speed railway will benefit remarkably from progressive maglev activities in the field of (tunnel) aerodynamics.
