ABSTRACT = {This work consists of evaluating the impact of the most relevant characteristics of railway vehicles, 
namely geometric, mechanical and aerodynamic properties, in their runnability in the presence of 
strong winds, more precisely in the risk of derailment. Such objective is achieved by performing 
several dynamic with a non-linear vehicle-structure interaction model developed by the authors 
[1,2] and used in other works in this field [3,4], which allows the evaluation of the wheel-rail contact 
forces and, consequently, the unloading index, as suggested by the European Norm EN 14067-6 [5]. 
The calculations are carried out for several scenarios characterized by different train and wind 
speeds. The wind is simulated with a stochastic model that allows the generation of turbulent wind 
time-histories based on power spectral density functions. The reference vehicle adopted in this work 
corresponds to the European InterCity Express 3 (ICE-3) train, whose original properties were 
parameterized to evaluate their influence in the vehicle’s stability. This parametric study focuses on 
the variation of several properties of the vehicle that may influence its dynamic behavior against 
crosswinds, namely the carbody mass, height of the gravity center, aerodynamic coefficients, and 
stiffness and damping of the suspensions. Apart from the suspensions’ properties, which prove to 
have a negligible influence in the vehicle’s stability, the remaining parameters have a significant 
impact in the running safety against crosswinds.},
