Study On Calculation Method For Passing Capacity Of Railway Passenger Dedicated Line

Passenger dedicated line is a hot topic of Chinese railway development these years. Many countries in the world have more perfect network of passenger dedicated line and their own feature on the management of dedicated passenger line. According to the actuality of our railway, we construct dedicated passenger line on the busy corridor in the construction forepart, and gradually found the network of dedicated passenger line. After founded dedicated passenger line, people pay more attention to the issues how to calculate the passing capacity and to use the capacity.This article researches on the calculation method for passing capacity of passenger dedicated line about three transportation styles, which are total high-speed, high-middle mixture and passenger-freight mixture, and obtains the deduction coefficient calculation method. Then propose the maximal capacity of train working diagram of passenger dedicated line and four evaluation indexes. And amend the deduction coefficient calculation method by using these indexes. Finally, taking Jingjin passenger dedicated line, Zhengxi passenger dedicated line and Shitai passenger dedicated line as example, this article calculates and analyzes the passing capacity of our three passenger dedicated lines by using above methods.
