Cross wind safety of rail operation has been a major topic for the last decades with respect to both high speed trains and also general rail traffic all over Europe. In Germany, operation of passenger railway traffic in cross wind has been regulated since the beginning of this century. However, freight vehicles have only become the focus of cross wind safety in recent years due to the introduction of modern, lightweight sliding-door wagons. In contrast, safety of cargo transport under the influence of strong winds in terms of fastening and fixation of loads has been studied a long time ago. Approaches to assess the stability of freight vehicles were developed analogue to those for vehicles of passenger traffic. These methods allow for appropriating the stability of vehicles in terms of characteristic wind curves (CWC) that show the permissible wind velocity in order to not succeed a pre-defined, still safe condition. On the basis of CWC the exposure of infrastructure to strong gusts can be evaluated and the combined safety of vehicle operation on a line can be assessed. Recent work on cross wind safety of freight vehicles focused on the advanced overall system of operational safety, i.e. the modelling of cross wind safety for the combination of vehicles and infrastructure. This document summarizes in depth the general safety assessment of railway freight vehicles operating under strong gusts.
