The Research Of Transport Organization Of Operating Heavy-haul Trains In Nanning Kunming Line

With the continuous development of social economy in our country, transportation demandgrowth is the basic trend, the expansion and efficiency improvement of the conventional linescapacity is one of permanent issues of railway transportation, domestic and foreign studies haveshown that the railway heavy-haul transportation is an important measure to enhance thetransport capacity and efficiency. The way of trains passing limites the single-track railway sothat it lacks of capacity, study the measures of single-track railway expansion, especially thetransport organization method to improve the transport capacity by heavy-haul trains, it has greatsignificance of theoretical guidance and engineering applications.The Nanning Kunming Line is an important transport channel in southwest of border area,which across Guangxi, Guizhou, Yunnan provinces (area). The economy develops rapidly andthe transport demands greatly in local area.Therefore, expanding the transportation is urgent.While, because of its poor infrastructure, it cannot direct use of heavy-haul line transporttechnology. Hence, according to the study, the existing device functions as a starting point,ourcountry forms the single-track railway heavy-haul transport mode, including our mountainoussingle-track electrified railway heavy-haul transport technology and standard method.In view of the above situation, this essay in the Nanning Kunming Line background studiestransport organization scheme of heavy-haul trains from the actual existing mountain single lineelectrified railway.The freight flow characteristics and situation of transport organization of Nanning KunmingLine. The essay analyses and studies the regional socio-economic of Nanning Kunming Line.The social transport demand is the foundation of railway traffic, Using the method ofmathematical statistics and regression analysis to predict the future development direction offreight rail capacity and provide data support for development of railway freight transportationand provide data support for development of railway freight transportation.The technical support and transport organizations research of mountain single-trackelectrified railway which has heavy-haul trains. The essay studies the existing transportorganization mode and heavy-haul trains transport organization of Nanning Kunming Line.Thetechnical support of mountain single-track electrified railway which has heavy-haul trainsincluding column tail unit upgrades, coordinate transformation of power equipment, vehicle inspection programs and other organizations. The essay also studies the optimized drawingproblem of Heavy-haul Train-A and gives the optimization program of Heavy-haul Train basedon the characteristics of heavy-haul transportation problem in Nanning Kunming railway lineand the modeling of job shop scheduling problem.The essay studies the transport efficiency of Nanning Kunming Line heavy-haul trains. Theessay focuses on the study of line capacity increasing condition and transport efficiency afterrunning the heavy-haul train in Nanning Kunming Line and predicts the application prospect,economy and social benefits.The essay studies the transport organization model and development of mountainsingle-track electrified railway which has heavy-haul trains. Based on the above theoreticalresearch, the system puts forward the transport organization scheme of running heavy-haul trainsin Nanning Kunming Line, according to the other mountain single-track railway’s characteristicsand needs of transport in our country, the depth of the model and technical conditions mountainsingle-track electrified railway which has heavy-haul trains, provide theoretical support for theimplementation of measures to reload expansion mountain single-track railway.
