Measurements show that, at high speeds, rolling noise is still the dominant source for both interior and exterior noise. Although rolling noise modelling has been investigated for more than 30 years, a train running at 350 km/h or higher along a non-ballasted slab track introduces a number of new factors which have not been adequately addressed in the past.
