FREE FIELD VIBRATIONS DURING THE PASSAGE OF A THALYS HIGH-SPEED TRAIN AT VARIABLE SPEED

During homologation tests of the high-speed train (HST) track between Brussels and Paris, free field vibrations and track response have been measured during the passage of a Thalys HST at speeds varying between 223 and 314 km/h. These experimental data are complementary to the other, but scarce, data sets published in the literature. Apart from illustrating the physical phenomena involved, this data set can be used for the validation of numerical prediction models for train-induced vibrations.
