Abstract: This paper discusses some problems encountered in the design of train control system in the complex hub renovation project, including the method to choose different transition schemes in the renovation project of adding train routes for a large EMU depot, the feasibility demonstration of taking the train control system to degrade the mode for maintaining the operation of transportation, and the analysis of failures due to inadequate track circuit design and simulation content found in the dynamic verification with EMU. This paper proposes some rules followed and issues that need attention in the designing transition solutions of train control system, which have certain reference value for the implementation of similar projects.

摘要： 探讨在复杂枢纽改造工程中列控系统设计工作遇到的一些问题，包括在大型动车所全站增加列车进路的改造工程中对不同过渡方案如何选择、复杂枢纽改造中由于过渡工程需要保持运营而采取列控系统降级运行的可行性论证以及在动车组动态验证中发现的由于轨道电路设计和仿真内容的不足而导致的故障分析。提出在复杂枢纽改造中的列控系统过渡方案设计和系统集成工作中可以遵循的规律和需要注意的问题，对类似工程实施具有一定的参考价值。
