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.
