In the present paper the force aerodynamic coefficients measured, according the European Standard Specifications, by means of wind tunnel tests carried out on a 1:15 scaled model of ETR1000 train in presence of different windbreaks configurations, are presented. In particular, 3m high band barriers (40% of porosity) have been tested with different gaps (from 0,5m to 30m, full scale) in the windbreaks and considering different positions of the train with respect to the gaps. The results shown in this paper allow to evaluate the effect of different windbreak parameters (gap amplitude, train position) on the train overturning risk and they represent a complete database for validation of CFD analyses.
