Abstract: The railways in the hub area of Zhenjiang include the existing Shanghai-Nanjing Intercity Railway passenger dedicated line, the Beijing-Shanghai High-speed Railway (from Beijing South Railway Station to Shanghai Hongqiao Railway Station) and the newly connected Lianyungang-Zhenjiang High-speed Railway (passenger dedicated line), all of which are controlled by CTCS-3 signal systems. In terms of the introduction of Lianyungang-Zhenjiang High-speed Railway into the hub area of Zhenjiang, it is not only necessary to ensure that the existing GSM-R network is not affected, but also to meet the network coverage demands of new lines. Therefore, reasonable optimization and adjustment measures need to be taken to satisfy the coverage demands of each line. In this paper, the GSM-R coverage scheme of this hub area is studied and the corresponding optimization scheme is proposed, which provides an idea for the optimization of the radio-sharing sections of multiple other CTCS-3 lines.
