The Analysis On Transportation Capacity And The Research On Transition Scheme For Reforming Guiyang South Marshalling Station

The railway station is the key component of the railway network. It is the critical locality of exchanging station vehicles stream, adjusting movement of trains and supplying transportation power, besides handling the related stations' trains operation, the technology and passenger and cargo services.The transport capacity of railway station is influenced by passenger and cargo transportation, disintegration of grouping, rolling stock , interval lines in stations, and so on. These equipments are correlative and correstricted. Their capacities are also correlative, and sometimes could transform mutually. Simultaneously, the layout of every equipments in stations and the operating organization of network vehicles stream are also affecting the capacity of stations. Along with the construction of Hu-Kun railway and gradual consummation of southwest railway network, the illogicality of capacity insufficient in Guiyang station is prominent unceasingly, and the unmatching capacity of stations and lines restricts the capacities of six big channels of ZHU lines and railway network. It has been put on the agenda to reforming Guiyang station. It becomes urgent affairs to investigate a transition scheme to ensure the transportation be safe and unimpeded during the period of reforming and extending Guiyang south marshalling yard.This paper mainly adopts the research method of system engineering. First, this paper analyzes the importance of Guiyang station to the local economic development, its current railway situation, central technique standards for linking up railways, existing technical equipments in station, and operation and characteristics at present. Then, according to these influencing factors, this paper analyzes the status quo of transportation ability, existent problems, and demands for traffic during constructon of marshalling yard, elucidates the measures to enhance transportation capacity, ensures the transport be safe and unobstructed during extending Guiyang station and adequately meets the needs of railway transport capacity after reformation and extension.
