Study Transit Time Of Long-distance Direct Freight Train At Marshalling Station

Railway transportation is one of the important ways of freight transportation in our country,especially the development of supply side reform in recent years.With the gradual improvement of railway infrastructure and the increase of the demand of social cargo owners,railway enterprises have actively increased the number of long-distance direct freight trains in various modes,but the transit time of the marshalling stations of the first long-distance direct freight trains has increased obviously because of the influence of various factors such as traffic gathering,scheduling efficiency,line capacity and transfer of machines.Transit time of marshalling station is an important index in railway cargo turnover time.The extension of transit time will lead to the extension of cargo turnover time.The extension of cargo turnover time will directly affect the timeliness of cargo transportation and the efficiency of locomotive and vehicle utilization,and will cause serious economic loss to railway enterprises and cargo owners.This paper analyzes the conditions for starting the long distance direct freight train,mainly judging from four aspects: marshalling station condition,interval operation condition,technical operation condition and transit time condition.This paper puts forward the theory of the transit time control of the train running on a long distance direct freight train in marshalling station.Taking the extension of transit time of yingtan marshalling station in 2017 as an example,this paper mainly analyzes the effect of long-distance direct cargo train traffic on transit time of yingtan to zhangping,yangfang,sanming and jiujiangxi.In this paper,the conclusion of the opening line is obtained by combining theory with practice,which is of great significance to shorten the compression of freight truck turnaround time,ensure the shipping time and improve the efficiency and efficiency of the enterprise.
