提高运输组织、技术组织水平,挖掘既有设备潜力,在能力限制地段提高行车密度,是缓解铁路运能与运量矛盾的重要途径.而在双线能力限制地段,适当调整列车运行时分,在该段采用“平图法”作图便是一项“短平快”的扩能措施.作者力求把问题提得更鲜明,论证更有理,数据更准确,措施更具体,具有一定实用价值. Increasing the level of transport organization and technical organization, excavating the potential of existing equipment and increasing the driving density in the limited capacity area are important ways to alleviate the contradiction between the capacity and the transport capacity of railways, while in the two-lane capacity limited area, the train operation hours This paragraph drawing on the “flat map method” is a “quick and easy” expansion measure. The author seeks to make the problem clearer, the argument is more reasonable, the data is more accurate, the measures are more specific and have some practical values.
