Abstract: Turnout control is divided into single-acting turnout and multiple-acting turnout control, and the multiple-acting turnout includes double-acting, three-acting and four-acting linkage turnouts, etc.. The design scheme of the turnout is directly related to the signal interlocking relationship. This paper analyzes the impact on the signaling system based on the different design schemes of the single-acting and double-acting turnout of the crossover, so as to enhance the awareness of safety control.

Key words: turnout, scheme, interlocking, impact, analysis

摘要： 道岔控制分为单动道岔和多动道岔，多动道岔又包括双动、三动、四动等联动道岔。道岔的设计方案直接关联着信号联锁关系，围绕渡线道岔单双动不同的设计方案，分析对信号系统的影响，以增强安全管控意识。
