On the influence of crossing angle on long-term rail damage evolution in railway crossings

The rails in railway crossings are subjected to severe load environment leading degradation of running surface due wear and accumulated plastic deformation. To compare long-term three fixed with different crossing angles, nominally designated 1:12, 1:15, 1:18.5, a multidisciplinary simulation methodology is applied predict damage the rail. For given traffic scenario, including up 65 MGT facing move passenger through route, results show that increases increasing angle. ratio between maximum for largest smallest angles found be about terms two Initially high rate deformation reduces significantly after first 2–5 MGT, 10–30 it approaches nearly constant value lower than rate.
