Abstract

The aerodynamic implications of freight trains travelling at operating speeds of up to 150km/h have been investigated, specifically tunnel pressure generated along the length of the train. Extensive experimental campaigns in the DLR-Göttingen moving-model facilities using reduced scale, generic freight train models and realistic loading configurations, have provided new insight into the problem. Industrial specific analysis and the subsequent results have generated recommendations for aerodynamic optimization of freight trains for high-speed operation.
