文章在分析我国铁路现状的基础上,指出“扩能”应从加强车流组织入手,以充分发挥线路和编组站的综合运能;提出进一步提高始发直达列车的数量和质量,搞好编组站的合理布局和分工,调整车流径路等三项有待研究的课题,并以1987年执行的列车编组计划为例作了说明。 Based on the analysis of the status quo of railway in our country, this paper points out that “expanding energy” should start from strengthening traffic flow organization so as to give full play to the comprehensive capacity of the line and marshalling stations. It is proposed to further improve the quantity and quality of the direct trains starting from the marshalling station Rational distribution and division of labor, and adjustment of traffic flow paths. Three issues to be studied are discussed, taking the train formation plan implemented in 1987 as an example.
