Abstract [en]

A model for determination of costs for track deterioration is presented. In particular, the model is able to discriminate between vehicles with different characteristics operating on the track, as well as incorporating operating data (speed, cant deficiency, etc.) and track geometry. The model is implemented in an Excel™ environment. Its use is exemplified by a Swedish case of mainline passenger and freight traffic. Some results are presented on the influence of vehicle characteristics, track geometry, track lubrication and speed. The model predicts that axle load, radial steering ability, unsprung mass and track lubrication are decisive for track deterioration and its associated costs.
