Running characteristics of rolling stock are assessed using a process defined in EN 14363. Track geometry is an essential parameter for this. This contribution describes methods for dealing with track geometry in the assessment process and some proposals for an improvement. Different types of track geometry characterisation are assessed on their effectiveness in describing the running characteristics in a regression model. The test data gathered in Dynotrain is used for this. Multiple regression is proposed to be used as a method to transform test data from one set of track geometry conditions to another set. This allows the quantification of the influence of track geometry on the vehicle's running behaviour.
