Abstract: It is difficult to avoid the crossing and merging of new high-speed railway and the existing lines, and the line conditions are more complex. This paper introduces the GSM-R system design and network optimization scheme for typical cross parallel lines and continuous tunnel sections of the recently commissioned Huzhou-Hangzhou high speed railway, Zhangjiajie-Jishou-Huaihua high speed railway and other lines, and gives specific wireless design solutions for scenarios related to multipath interference, level inconsistency and poor quality caused by wireless interference. Finally, it summarizes the experience of these projects, and puts forward reasonable engineering suggestions schemes for similar railway sections.

Key words: high speed railway, parallel section, continuous tunnel, railway digital mobile communication system, network optimization
