WebThe robustness is achieved by optimising the crossing geometry for a representative set of wheel profiles. As a basis for the optimisation, a crossing geometry is created where rail cross-sectional profiles and longitudinal height profiles of both wing rails and crossing nose are parameterised. WebA double crossing with bent out check rails is arranged in the area of the obtuse-angled meeting of the two lines of rails. Regular crossings have a slope of 1:9 and are no longer fitted without swing nose crossings in tracks with a maximum speed of over 100 km/h. Crossings with a flatter angle than 1:9 are constructed with swing nose crossings. custom built pavilions
