Research On The Method Of Making Heavy Haul Train Diagram On The Mengxi-central China Railway

Heavy haul train represent the advanced level and important developme nt direction of railway freight in the world today,and are the main means for improving freight transport capacity.Train diagram is a comprehensive plan for heavy haul railway transportation organization.The quality of its preparation will directly affect the safety and efficiency of heavy haul railway transportation work,affect the degree of adaptation of the railway system to meet socio-economic development,and therefore the train scheduling for heavy haul railway issue is a key aspect of studying heavy haul transportation.Studying the train scheduling for heavy haul railway needs to be combined with the characteristics of heavy haul transportation and proposing a method for the compilation of train diagrams in order to improve the efficiency of heavy haul transport,promote the development of heavy haul transportation for railway enterprises and provides the basis for formulating scientific and reasonable heavy haul transportation strategies.On the basis of summarizing the existing research results,this paper combines the key issues and preparation methods for the compilation of the train scheduling for heavy haul railway from Mengxi to Central China Railways.The main research contents of the thesis include:(1)The paper analyzes the theoretical basis for the preparation of train diagrams for heavy haul railways,elaborates on the relevant contents of heavy haul transportatio n organization and the train diagram of heavy haul railways,and combines with the theoretical basis to make analysis and explanation of the overview of the Menghua heavy duty railways.(2)It studies the key issues in the preparation of the train diagram of heavy haul railways in conjunction with the Menghua Railway and focuses on such related issues as the reasonable departure time range of heavy haul trains,the setting of the time window plan,the paving of trains' operating lines at train combined and decompositio n station,and the turnover of locomotives;it discusses and proposes the layout method of the time window plan of Menghua Railway and the method of laying out the running line of the adjacent section of the combined and decomposition station.(3)Based on the study of the key issues of the Menghua heavy haul railway train diagram,it summarizes the ideas and principles for the preparation of heavy haul railway train diagrams,and builds a heavy haul train operation plan drawing model;meanwhile through model characteristics it designs the corresponding particle swarm optimization algorithm,combining with Menghua railway line as well as train plan data verifies the model and algorithm;the results show that the method proposed in this paper and the compiling model are feasible.This paper studies the problem of the preparation of heavy haul train diagrams based on the Menghua Railway,and analyzes in detail the key issues in the preparation of train diagrams.The relevant methods proposed in the paper are based on the specific operating conditions of Menghua heavy haul railway;although they have certain the limitations,the proposed method for the preparation of the train diagram has a certain degree of practicality,has a good guiding significance for the train scheduling for heavy haul railway.
