| Abstract | An analysis of existing track geometry data is described from which the signatures of key track geometry variations related to severe track-train dynamic interaction are identified and quantified. Mathematical representations of these signatures are defined and presented. Track geometry descriptors used to monitor these key signatures are determined. Applications of these descriptors in terms of present track geometry measurement techniques are described. Statistical analysis of these descriptors is performed and the results are presented. Based on limited data preliminary results to quantify changes in these descriptors with time are presented. |
