Analysis On Capacity Of Zhengzhou North Marshalling Station

Zhengzhou North Station is located at the intersection of the Beijing-Guangzhou line and the Longhai Railway,the station according to the nature of the technical job marshalling yard,according to the business nature of the freight station,according to the volume of business for the principal station stations of the type oftwo-waytandem three eight field,under the Zhengzhou Railway Bureau.According Zhengzhou North Station provides tonal,atonal transit trains use amount,and other operations of the standard time,according to the system viewpoint and method to calculate the capacity up and down the system to reach the field,the starting field,Hump disintegration and hump tail formation capacity utilization as well as uplink system's arrival,disintegration,grouping,starting capacity respectively are 102,89,102.7,158.5;downlink system's arrival,disintegration,grouping,starting capacity respectively 122.6,113.3,147.8,175.8.From this we can know,the restriction point of uplink system and downlink system in station are both hump disintegration capacity.According to the traffic flow in the system circuit,grade eight at the station layout brings issues that traveling long distances,increased working time;the station traffic plan and the shunting locomotive application mode,causing both amount of work fo upper and lower system and capacity utilization unbalanced,.According to capacity adaptation problems,we propose adjustments to the traffic plan which use the exchange to adjust system for uplink and downlink operations and adjust technical measures like adjusting locomotive number and so on Thus,Zhengzhou North marshalling station will play a greater role in road network.
