Discussion on Special Scenarios of Switchable Balise Group for Large Number Turnouts in CTCS-2 Level Train Control System.

This paper firstly describes the setting of switchable balise group for large size turnouts and the method of sending telegrams in the high-speed railways. Then an analysis is conducted on the reasons for train speed reduction when passing through large turnouts in special scenarios such as inconsistent telegram data, insufficient distance of approaching sections and short sections. Finally, it summarizes several types of problems frequently encountered in engineering design and data compilation, and proposes the corresponding solutions, which have certain guiding significance for improving the operational efficiency of high-speed railways.
