Abstract: The introduction of high-speed railway lines into hubs brings challenges to the design of signaling system. Combined with the introduction of Beijing-Shenyang Passenger Dedicated Railway into Beijing hub, this paper proposes optimization schemes from the aspects of the selection of train control level in the hub, automatic trigger at the liaison boundary between yards, and improving the overall operation efficiency of the hub, so as to serve as a reference for other similar projects.

Key words: optimization design, hub, high-speed railway, train control level selection, liaison boundary between yards, automatic trigger, improving efficiency

摘要： 高速铁路引入枢纽给信号系统设计带来挑战，结合京沈客专引入北京枢纽，从枢纽内列控等级选择、场联分界处自动触发、提高枢纽整体运行效率等方面提出优化方案，以期对其他类似工程建设起到借鉴、参考作用。
