Special section wing rail

The utility model relates to a special section wing rail which is used for constituting railway switches and frogs. The front segment of the special section wing rail is rolled into a standard rail, and is connected with a guide rail. The middle changes gradually from a special section segment to a standard rail section, and then is welded with a standard rail of required length to meet use requirements. The rail web and the rail bottom of the special section form symmetrical state, the symmetrical centre line of the rail web and the rail bottom deviates outwards from the centre line of the rail head of the standard rail segment, the width of the rail head to the inside of the centre line of the rail web is bigger than the outside, and the rail head forms asymmetrical state. All items of mechanics performance indexes of the special section of the utility model are obviously better than the mechanics performance indexes of the existing wing rails such as the inertia moment of horizontal shafts, the maximum tension stress born by rail bottoms, etc.
