The relative significance of vehicle dynamics on the dynamic component of wheel-rail interface vertical forces caused by relatively short wavelength track perturbations is estimated, based on a simple dynamic model, for a range of suspension design types. The results indicate the relative importance of suspension design on track damage. This study is analytical. However, it provides a basis for testing to ensure that the influence of suspension design on track-induced vertical loads is better documented and understood.
