Railway rail has asymmetric rail head profile formed by combination two standard of rail profiles, such that radii of curvature is decreased from bar center towards running edges
摘要
<p>The railway rail has asymmetric rail head profile in which radii of curvature is decreased from the bar center towards running edges. The asymmetric rail head profile is formed by combination of rail profiles 60E1 and 60E2 in accordance with DIN EN 13674-1.</p>
