Track Dynamic Behaviour at High Frequencies. Part 2: Experimental Results and Comparisons with Theory

SUMMARY Three theoretical models, simulating the dynamic behaviour of railway tracks at frequencies up to 5 kHz are presented in a companion paper [1]. In this paper, experimental results obtained on several European tracks are presented. The validity of the models is assessed by means of comparisons between experiments and simulations: generally a good agreement is found. Recommendations are given for further improvements.
