单线铁路CTCS-2级列控系统设计应用研究

CTCS-2级列控系统主要应用于双线铁路,在单线铁路中尚无工程应用先例,为解决单线铁路CTCS-2级列控系统应用存在的问题,在符合现行规范、不修改列控车载设备的前提下提出CTCS-2级列控系统总体方案。通过单线铁路与双线铁路的差异性对比分析,结合CTCS-2级列控系统功能需求,对闭塞方式、轨道电路配置、应答器设置、临时限速管理等特殊技术问题进行了研究并提出了解决方案。研究表明:CTCS-2级列控系统应用于时速200～250 km单线铁路能够实现列车高速安全运行。

Design and Application of CTCS-2 Train Control System in Single-track Railway

CTCS-2 Train Control System is mainly applied in double-track railway, until now, there is no engineering application precedent in single-track railway. In order to solve the problems in the application of CTCS-2 Train Control System in single-track railway, the overall scheme of CTCS-2 Train Control System is proposed in compliance with the current regulations and under the premise of not modifying the on-board equipment. Through comparative analysis between single-track and double-track railway, combined with the functional requirements of CTCS-2 Train Control System, specific technical problems are studied and solutions are proposed, in respective of track circuit configuration, Balise setting and temporary speed limit management. The results prove the safe application of CTCS-2 Train Control System in high-speed operation of 200～250 km/h on single-track railways.
