Capacity Analysis And Transportation Organization Optimization Of Wuhai West Railway Station

With the rapid development of railway construction in our country and the continuous expansion of network,the railway freight demand and freight volume is also rising,but the sudden outbreak of the new champions league plus freight market increasingly fierce competition,cause the fluctuation of supply and demand structure of railway transportation gradually increase,the traffic structure and flow variations is bigger,faster,This also brought new opportunity and challenge to railway cargo transportation.In this increasingly complex background,the transport capacity of some technical stations is relatively insufficient,and the incoordination of the point-line capacity is becoming more and more prominent.At present,how to make good use of the existing technical equipment and production personnel to maximize the transportation capacity of key technical operation stations is the key research direction of the busy trunk transportation organization work of railway bureau group companies.The key technical operation station not only decides the convenience of goods turnover,but also profoundly affects the transportation order and efficiency of the trunk channel.Considering departure line capacity,throat through capacity,loading and unloading car ability and adaptation ability to the station and other kinds of factors,on the basis of analyzing technology station to carry out the ability to use,finds out the factors restricting the station capacity,according to the actual situation to reinforcing,improvements,changes and adjustment,further play the station transport capacity,do point line matching,the reasonable coordination,It has very important practical significance in the practice of first-line transportation production.Wuhai West Railway Station is the boundary station between Hohhot Bureau and Lanzhou Bureau.The station connects to the four directions of Bao-Lan upstream and downstream main line and Wu-Ji Line,and connects to the special lines in six directions at the same time,not only bear the Bao-Lan railway direct,straight,extents,trainset,overrun,small Wu-Ji line operation of freight train marshalling,dissolution,adaptation and so on homework,In addition,it is also responsible for loading,unloading,fetching and sending operations of freight yard,special line and section pipeline,as well as the terminal,departure,transfer,stop and other related operations of passenger cars.As a result,the capacity utilization rate of arrival,departure and shunting lines is tight,and the congestion is serious during the busy period.In addition,according to the plan,the direction of the Wu-Ji line connecting the station will also open Bayinaobao station in the near future,which will also have a certain impact on the organization of traffic flow and capacity utilization of Wuhai West Railway Station.The last capacity assessment of Wuhai West Railway Station was carried out three years ago according to the requirements of the Transportation Department of Hohhot Bureau Group Company.It adopted a realistic way of following the shift.During the internship,the new workers filled in the station capacity assessment realistic table,summarized and sorted out,and calculated the final transport capacity of the station.This way of assessment is not suitable for the actual situation of now,the original manual are leaky realistic way,data is not complete,the existing microcomputer interlocking playback function of the monitoring system,can inquire the station at any time any day’s homework,more efficient and more comprehensive data,original ability assessment of realistic peak time selection is the end of the work,The calculated results are too high to represent the operation of the station throughout the year.Therefore,it is necessary for this paper to carry out the research on capacity identification realism.The main difficulty lies in determining the time range and period for collecting realistic data.It is necessary to conduct in-depth analysis and comprehensive determination according to the equilibrium degree and changing trend of the station traffic flow.Based on the research and analysis of the methods of station transport capacity identification at home and abroad,this paper determines the method of Wuhai West Railway Station capacity identification based on the optimization and adjustment of the existing methods.Combined with the current production organization of the station,starting from many factors such as train disassembly,crossing vehicle delivery,special line pickup and delivery,through the tracking and reality of the field operation,on the basis of comprehensive relevant data,the utilization rate calculation method is used to determine the station to the departure line passing capacity,throat passing capacity and adaptation capacity.On this basis,the restrictive factors for improving Wuhai West Railway Station’s transportation capacity are analyzed,and scientific and reasonable suggestions for optimizing station capacity expansion are put forward based on the actual situation of Bayinaobao Railway Station,which will be opened soon.In the process of research,the paper from the station capacity assessment realism and station capacity calculation of two aspects,under the support to get a lot of traffic data,in-depth analysis of the station traffic characteristics and trends,after selecting realistic time to represent the normal operation of the station,the ability to check set realistic data can be more close to the actual situation,The train at the same time to the original hair car take throat switch group time calculation formula for correction,make the results more accurate,in combination with the special case of separating mouth station,puts forward the feasible station transport organization optimization measures,research results of the Wuhai West Railway Station capacity assessment,operations ability to transform the traffic organization optimization,etc.Provide technical support to the theory.7 pictures,37 charts and 50 references.
