既有繁忙干线列车提速运输组织的研究

Research on Transportation Orgnization in the case of Raising Train Speed on Existing Busy Lines

论述了客车提速对线路区间货物列车通过能力的影响，分析了货物列车提速和压缩追踪列车间隔时间对提高线路区间通过能力、弥补客车提速产生的能力损失的作用，论证了既有繁忙干线列车提速后，列车质量、速度、密度合理匹配的可行性和具体方案。

This paper describes the impact on line capacity in respect of cargo trains due to raising passenger train speed.It analyses the positive role of raising cargo train speed and reducing train interval time in enhancing line capacity in respect of cargo trains to make up the capacity loss due to raising passenger train speed.It also discusses the rational matching schemes for train weight,speed and density after speed raise on existing busy lines and the specific schemes for Jinghu,Jingguang,Jingha and Longhai Lines.
