Abstract

The DLR FR8-LAB is a self-contained swap-body container, equipped with an on-board power supply, data acquisition system and remote-access communication capability has been transported on normal operating freight-trains in Europe. Initial measurements have demonstrated the ability for the on-board systems function in the challenging industrial conditions. Surface pressure measurements, as well as lidar and thermal cameras have demonstrated the FR8-LAB can be used to characterize the aerodynamic conditions and coupled them with the operating scenario. Generic, representative conditions that a container on a typical freight train would experience can be characterized. Further, specific operating scenarios such as: entering/exiting tunnels, travelling over bridges, or passing other rail vehicles - that could exhibit aerodynamic characteristics with increased aerodynamic drag (low operating efficiency) or reduced crosswind stability (potential safety concern) - can be characterized in detail.
