发明名称 Railway switch comprising a frog having a movable main point and auxiliary point
摘要 In a railway switch comprising a frog having a movable main and auxiliary point, the main and auxiliary point are formed by using thick-web standard rail sections and asymmetric tongue profiles of smaller height as compared with the thick-web standard rail sections which are arranged as outer wing rails. The difference in height between the height of the main and auxiliary points and the height of the outer wing rails is greater than the height of the rail feet of the main and auxiliary points.
