Passenger Dedicated Line Comprehensive Maintenance Skylight Selection To Regional Pass Capability Impact Analysis

With the development of construction of the Passenger dedicated Line,the issues relating to transportation organization need to be solved urgently.The train on the Passenger dedicated Line has the feature of high density,high speed,and high maintenance standard.How to set the “sky-window” in the train operation diagram to ensure the maintenance of public works,electrical engineering and contact system is one of the most important issues.During the research,the author adopted the method of uniting analogy with qualitative analysis and quantitative account to analyze the reasonable all-around maintaining sky-window scheme considering the varied working manner,traveling organizing mode,configuration of ballast less track and the passenger special line net on the basis of sufficient domestic and overseas reference.Primary study includes:(1)Summarizing maintaining experience overseas and in domestic existing railway,ascertaining the requirement of passenger special line,then bringing forward the time demand of maintaining sky-window.(2)Analyzing the characteristics of transport demand for passenger special line systematically in our country and put forward the short-time demand of sky-window.(3)Common principle of setting up sky-window for passenger special line has been obtained from analyzing how the different sky-window forms affect organization of train operation.(4)Analyzing the characteristics of ballast less track servicing and ascertaining length of the sky-window.(5)The characteristics of transport organization for the different sky-windows are studied and the existing contents are pointed out.The influence of various sky-windows on passing capacity and the loss value of capacity are pointed out.
