✦ Synopsis

Surface roughness on 150 railway wheels and on the rails of 30 sites in the Netherlands have been measured. Block braked wheels were found to show higher roughnesses than the rail at any site. The smoothest rail is 8 dB smoother than the smoothest wheel. It was concluded that in reducing railway rolling noise NS must start to find ways to lower wheel roughness. Only after block brakes have been either removed or optimized will the rail require any attention. An exception to this rule is rail corrugation, which was found to occur locally. A good correlation was found between wheel and rail roughness levels and pass-by sound levels. Also, it was shown experimentally that wheel and rail roughness levels contribute with equal weight to noise production.

For several years, studies carried out in Europe have shown the need to consider wheel and rail surface roughness as a major excitation parameter in railway rolling noise. Measuring the rail roughness may be critical in the assessment of the noise created by the wheel/track system. It can be measure
