Abstract: Based on the double-line reconstruction project of Sangzidian railway station on Handan-Jinan railway, this paper proposes a special processing scheme for connecting turnout of switching lead when this turnout has been removed. In order to ensure safety of railway traffic during the signal transition, switch normal indication of transition turnout is inserted into the lighting circuit of protection signal. According to the different position and enable timing of inserting turnout, practical treatment methods of transition turnout control circuit are proposed separately, so as to meet the needs of railway transportation. The processing method of inserting turnouts in the switchless section during the transition period is discussed, and a reasonable transition plan is proposed to successfully complete the station signal transition. Through the summary of the signal transition scheme in the process of station transformation, these suggestions presented in this paper can supply references for transition scheme for station reconstruction project in the future.
