In this paper an extensive test has been described in which simultaneous measurements of the dynamic behaviour of both the vehicle and the track were made. Additionally, the resultant deterioration of the track was also measured at regular intervals. These results were interpreted and the dynamic reaction of track due to a passing vehicle were shown. The measurements were also used to develop and validate a comprehensive mathematical model to predict the performance of current vehicle/track systems as well as to predict the rate of settlement change and the future condition of the track. Through these results an improved understanding of the degradation modes in the vehicle/track system is established. Hence, by analysing the low frequency dynamic vertical vehicle/track interaction, track roughness can be predicted and the subsequent dynamic wheel loads can be evaluated with respect to acceptable track component load limits. Furthermore maintenance intervals can also be predicted proactively.
