Study on Train Working Diagram of Jing—Hu High-speed Railw ay Line Based on Railway Network

Train working diagram (TWD) plays a very important role in railway transportatio n, and it is the synthetic plan and foundation of railway transport organization .TWD worked out with computer is a practical and difficult project, which must b e solved as early as possible. Through many years research and practice,TWD work ed out with computer makes great progress not only in theory but also in practic e, which breaks into several periods, such as double track line,single track li ne,railway terminal area and railway network. Jing—Hu high-speed railway line, being programmed and built in the Tenth ″Fiv e Years Plan″, will take the mode of high-speed train and middle-speed train sharing high-speed railway line at beginning. So this results in big problem in theory and method of TWD between high-speed railway line and the existing rail way. Based on analyzing production and literatures of China and overseas about T WD of high-speed railway line and the existing railway, this paper establishes the theory of TWD of high-speed and middle-speed train using the same high-sp eed railway network train working diagram (HSRNTWD) .The main contents of this p aper are: (1) This paper analyzes and summarizes production and existing problems of TWD o f high-speed railway line and the existing railway in China and abroad. It desc ribes the differences and common grounds between TWD of the existing railway and high-speed railway line from many core problems such as aim, order and policy of TWD. (2) Based on the transportation mode of high-speed railway line and absorbed th e experience of TWD of the existing railway, this paper puts forward fundamental theory of TWD of high-speed railway line based on railway network, discusses a im, order and hierarchy of TWD of high-speed railway line. (3) This paper establishes the theory of high-speed railway line based on railw ay network from microscopic layer and macroscopic layer. Macroscopic layer is us ed to describe the network structure and relation of railway line, and calculate s the running path of high-speed train and middle-speed train; in microscopic layer, station plane diagram is made up of track circuit, turnout, curve, cross -over, main line or serial number of the station track center. Microscopic laye r is used to calculate and describe the train arriving route, departing route, p assing route, parallel route and conflicting route and so on. (4) Based on analyzing the scope of rational time for train departure and arriva l, this paper brings forward a method to calculate and decide the rational scope of time for departure and arrival of the cross-line middle-speed train. (5) Based on the theory of HSRNTWD, aims at the best convenience, best service f or passengers and good running order for train, this paper establishes a mathema tic model of TWD of high-speed train and middle-speed train running on Jing—H u high-speed railway line, and designs algorithm of FCSFQYGDPUF for this model. (6) For the sake of advancing equilibrium indices of TWD of high-speed railway line, this paper builds a mathematic model to get an initial plan of TWD of high -speed railway line for distributing points and designs an application algorith m of DCKDCRF to seek initial time plan of departure and arrival of high-speed t rain and middle-speed train sharing the Jing—Hu high-speed railway line. (7) For the aim of optimizing the quality of TWD of high-speed railway line, th is paper establishes the mathematical theory of stations lines of high-speed ra ilway line and designs the algorithm of ZXBLBHF to seek the answer to mathematic model. (8) This paper analyzes the running characteristics of high-speed train under t he situation of moving different distances and the use mode of EMU on the high- speed railway, and discusses several modes of integration between EMU and high- speed train, and builds a mathematic model to minimize total detention time of E MU; based on the study of locomotive facilities on the high-speed railway and t he mode of middle-speed locomotive routing, this
