Abstract: Proper train operation organization is an important guarantee to improve the station operation efficiency. As important equipment to ensure the train operation safety, the signaling system should be able to meet the needs of station train operation organization in route setting. In this paper, the Xinjie station of Baotou-Xi'an Railway is taken as an example. On the basis of the train operation organization adjustments proposed by the transport department, on-site verification and analysis are conducted to identify the problem in train operation organization after adjustments are made according to the current situation of existing stations. After research and traction calculation for train operation, the adaptive modification scheme of adding a route signal to the existing station signaling equipment is put forward to meet the special needs of train operation organization, which provides an idea for the future solution to such a problem, and provides technical reference for similar problems in engineering design.

Key words: train operation organization, traction calculation, signaling modification, ten-thousand-ton train, train operation speed

摘要： 良好的行车组织方式是提升车站作业效率的重要保障，而信号系统是保障行车安全的重要设备，信号系统应能满足车站行车组织作业办理进路的需求。以包西铁路新街站为例，根据运输部门提出的行车组织调整，通过现场验证及分析发现既有车站现状适应调整后的行车组织所存在的问题，经研究及行车牵引计算，提出对车站既有信号系统增设进路信号机的适应性改造方案以满足特殊行车组织作业的需求，为以后解决此类问题提供思路，为工程设计中的类似问题提供技术参考。
