双动道岔设置的合理与否 ,将直接影响行车安全 ,现以 2个不同站场为例 ,谈如何正确合理地设置双动道岔。1　缩小故障范围某中间站站场平面布置 (下行咽喉 )如图 1所示。原设计是将 5#道岔和电动脱轨器 TGQ按假双动道岔处理。经实际运用发现 ,由于 TGQ由电动转辙机牵引 ,且经常 Whether the dual-action turnout is set up rationally or not will directly affect traffic safety. Now, taking two different stations and yards as an example, how to set up the dual-action turnout correctly and reasonably? A narrowing fault range An intermediate station layout (down throat) as shown in Figure 1. The original design is the 5 # turnout and electric derailer TGQ double false points double turnout processing. The actual use of the discovery, due to the TGQ by the electric switch machine traction, and often
