Abstract
Rail roughness must be kept under control in a test site to ensure that it remains valid for type tests even some time after grinding. The paper presents the results of an analysis conducted on a high-speed track in Italy. Roughness measurements were carried out monthly for one year, starting one month after grinding. The analysis made by using a modified version of the long roughness measurement protocol gives a significant insight of the roughness growth phenomena.
