Abstract： Inaccordance with China State Railway Group's requirements for e-ticketing services“dual channels， dual routing，and dual power supply”the Zhongxing transmisson network on the Hanyuan Line was optimized and reconfigured to enhancethe security of e-ticketing communication paths.This work aims to eliminate the impact of single points offailure in transmission equipment and to ensure safe，stable，and reliable system operation.Basedon the SDH（Synchronous Digital Hierarchy） transmission system，this paper mainly describes how the retrofitof the existing transmission network on the Hanyuan Line achieves dual-route protection for e-ticketing services，thereby maximizing the safety of the e-ticketing channels.
