Abstract
In setting of the cross connecting line in dedicated passenger railway line,No.42 large size turnout is selected for the main line and the setting principle of Balise group for large size turnout is analyzed in the light of engineering practices. When the over speed limit of the fixed speed limit is set smaller than that required for the siding of the departure section,the EMU is subjected to over speed risks. Through the analysis and study of the setting of the large size turnout Balise group and the principle of the message transmission,this paper calculates the length of routing,and theoretically analyzes whether there are occurrences of over speed of the EMU in special scenes. The results show that when the side-access signal with large size turnout is open to the USU and the side-way connection is made,and at the same time,the permissible length of routing exceeds the braking distance range,and there is no temporary speed limit less than that of the lateral allowable speed for large size turnout,the train control center can send large size turnout data packages; meanwhile,in the departure section,when there is a fixed speed limit in the range of braking distance,which is less than the lateral allowable speed for large size turnout,EMU train will be in operation without over speed.关键词
