Problems About Speed Increasing of Train on Main Railway Lines

在对列车提速的必要性、原则和有限目标进行论述的基础上，就列车提速对运输技术设备的要求和运输组织方面的若干问题进行了初步探讨，分析了多速度客货列车混跑时，不同速度配比的组合方案对线路通过能力的影响。

Based on the statement on the necessity, the rules and limited objects of train speed increasing,the demands on transport technique equipment and for several problems about transport organization of train speed increasing are simply studied.The influence on transport capacity while passenger and freight trains are operated with different speed on one line is also anayzed.
