铁路货物列车列检作业间距设置的研究

Research on Setting Time Interval for Freight Train Examination

增大列检作业间距,延长列检安全保障区段,是提高铁路列车运行速度和运输效率的主要方法之一。西欧各国列检作业大多采用站检和“周”检方式,美国等国家列检作业是以终到检查为主。我国铁路列检作业间距设置从建国初期至今经历了四个阶段,现已明确提出了列检作业间距设置标准。针对影响我国铁路列检作业间距设置的诸多制约因素,提出延长列检作业间距的主要工作内容和设想是:根据检查对象的分类,调整作业组织结构和检查范围;利用信息化手段对车辆进行动态监控;研究和探索长大且固定编组的循环车组和青藏铁路1000km以上的列检作业间距设置模式;开展铁路车辆配件的可靠性研究。

One of the ways to raise train speed and transport efficiency is to prolong time interval and extend safety section of freight train examination. In view of the factors affecting time interval of freight train examination, main works to prolong time interval envisaged in this paper includes: adjust organization of examination according to classification of freight train; use IT technology to carry out dynamic monitoring of freight train; make study on reliability of train components, etc.
