Measurement of the aerodynamic pressures produced by passing trains

This paper describes measurement of the aerodynamic pressures produced by a Bombardier High-Speed Nonelectric Locomotive (HSNEL) on an adjacent stationary double-stack freight car. Static pressures are measured on the near and farside faces of the freight containers over a range of locomotive speeds from 60 to 130 mph. This data is also compared with the pressures predicted by computational fluid dynamics (CFD) simulations.
