Abstract: Taking the Huanglou block post of Lianzhen railway as an example, which has 10 sets of large-number turnout with No. 42 crossing number, and several high-speed rail lines connected with it to meet the needs of high-speed EMU trains and improve railway transport efficiency. Combining with the special situation of the block post with through route, which at the same time containing several groups of large-number turnout, this paper studies and discusses the setting principle of the large-number turnout balise group, especially the setting scheme of the continuous large-number turnout balise group, analyzes the special situation of balise telegram sending of large-number turnout, puts forward the corresponding technical solution, and makes a comparative analysis of the advantages and disadvantages from the aspects of operation safety and transportation efficiency, which can be used as a reference for the following railway engineering design.
