Main Line stations between the two crossing lines throat area allows the use of lateral speed of 80KM / H high-speed turnouts. Extension Station under the difficult conditions of the large turnout may be on the 12th. Tie-line and high-speed line connecting the positive turnout turnout symmetry should be determined by the highest rate quote based on the train, allows the use of the lateral speed of 160KM / H or sideways allows speed 220KM / H-speed turnouts. On the railway turnouts, there are some complex conditions not on the general track. For example, the existence of a fixed rail line interrupted frog turnout symmetry model, the impact of sharp angle rail, guard rail and wing rail is far greater than a curved track, vertical and lateral stiffness variation turnout area is much higher than ordinary rail tracks and so on. Locomotives when passing through turnout turnout symmetry, the force between wheel and rail lines will be much higher than normal. So part of the conservation effort turnout than the average track length of more equal, but also the life of the main components of the turnout track shorter than normal. For these reasons the wholesale symmetrical turnout, turnout has always been considered to be a weak link in orbit, and often affects a major cause of traffic safety and limit the speed of traffic, but also the focus of conservation efforts we put turnout reasons. Symmetrical turnout model, Inner Mongolia symmetrical turnout, Xin Yang machinery provided by Lin Xin Yang Machinery Industry Co., Ltd. Taizhou. Forest City Xin Yang Machinery Industry Co., Ltd.
