Haigermoser, A, Bezin, Yann, Coudert, F, Eickhoff, B, Grabner, G, Kraft, S, Thomas, D and Zacher, M (2013) On the influence of track geometry quality on the running characteristics of the vehicles – results from the EC-founded research project DYNOTRAIN. ZEVrail : Zeitschrift für das gesamte System Bahn, 137. pp. 2-14. ISSN 1618-8330

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.
