Renovation of existing lines with Turnouts is still used in the double switch rail track within the framework of the basic structure of the conversion. In addition to the basic framework of the tip rail track between segments of tight vertical load to bear, but still within the full length of the tip rail wheel-rail interaction withstand the horizontal forces. The basic process with standard gauge rail track in the tip section of tight under the rail head palate as 1: 4 or 1: 3 miter single turnout plant, with a sharp tip rail corresponding hidden profiles constitute a single turnout company structure in order to improve security and strengthen the tip section of track near the tip of the reverse operation. In order to be able to adapt turnout among cross laying CWR need long welded joints turnouts achieved great development, Japan, Germany, France, respectively, in situ pressure welding or thermite weld rail joints eliminate turnout area (insulated joints using cementation). Movable frog wing rail and using extended set of Straight telescopic ramp joints. In sharp track heel rut with stopper replaced with iron in order to resolve the rail temperature interval force transmission problems. Single turnout turnout single wholesale _ _ Xin Yang machinery provided by Lin Xin Yang Machinery Industry Co., Ltd. Taizhou. Forest City Xin Yang Machinery Industry Co., Ltd.
