This report presents measurements of geometry changes in railway turnout components. Cross sections of the crossing component and the blade component are measured by means of a so-called Miniprof equipment. The measurements show that large plastic deformation is a relevant damage mechanism as compared to other damage mechanism such as wear and crack propagation. Moreover, the results are believed to be important for the evaluation of numerical predictive models.
