摘　　要：列车越行是影响铁路列车运行图质量的重要因素,作为运行图编制优化的环节之一,列车越行有效性问题研究十分重要。根据列车在站间及区段内运行时分的不同,定义站间及区段同种类列车,提出列车越行的充分必要条件,在此基础上给出列车越行有效性的判断方法,研究提出区段内同种类列车的越行为无效越行,以达成、襄渝线列车运行图为例,对列车越行有效性评价方法进行验证。结果表明,列车越行有效性评价方法能够为运行图优化提供参考。Train overtaking is an important factor influencing the quality of railway train working diagram, and as one of train working diagram optimization links, its effectiveness study is very important. According to the train operation time difference between stations and railway section, this paper defines the types of trains between stations and railway section, and puts forward the sufficient and necessary conditions of train overtaking. Based on above, the paper provides judgment methods for train overtaking effectiveness. The study result shows that the overtaking of same type trains in railway section is invalid. Through taking the train working diagrams of Dazhou-Chengdu line and Xiangyang-Chongqing line as examples, the evaluation method of train overtaking effectiveness is validated, and the result shows the evaluation method could provide references for train working diagram optimization.
