为了提高机车的运用效率,必须使列车运行线与机车周转密切协调。在研究机车周转图中,列车运行线组包含的列车对数与机车全周转时间之间的关系的基础上,提出了单一周转图和分组周转图的铺画条件及综合分号运行图中抽减运行线的方法。为使抽减的一组运行线不至于影响其余运行线的机车周转,被抽减的运行线应当是由1台或1组独立的机车牵引的。这一方法为铺画机车周转良好的列车运行图提供了理论依据。
In order to improve the efficiency of the locomotive, the train running line must be closely coordinated with the locomotive’s turnover. Based on the study of the relationship between the number of train trains and the full turnaround time of the locomotive train line group, the paper presents the drawing conditions of the single turnaround diagram and group turnaround diagram, Reduce the line of operation. In order for a reduced set of operating lines to not affect the turnaround of the remaining operating lines, the reduced operating line should be towed by 1 or 1 independent locomotives. This method provides a theoretical basis for the drawing of a good train running diagram of locomotives.
