Research On Capacity Coordination Of Marshalling Station

With the development of social economy, railway infrastructural investment is increasing continually, speed-raising and adjusting operation diagram have been done six times by now and the traveling speed of existing passenger train and goods train is increased on a scale. Because of passenger train and goods train running on the same railway, the arrival and departure of train on the marshalling station is imbalance by stages, which has a big effect on the transportation organization of marshalling station.The paper researches the capacity coordination of marshalling station on the background of the current status that the departure and arrival of train on the marshalling station because of the speed-raising of the train running on the existing railway and the operation of transportation products, capacity coordination is analyzed in two aspects: the capacity coordination among sub-systems in the inner of marshalling station system and coordination of point and line capacity between the interval of railway and arrival-departure system of marshalling station.The research of capacity coordination is complex on the basis of imbalance transportation. Firstly, the paper analyzes the coordination relations among sub-systems of the marshalling station and calculates the capacity of arrival and departure track, breaking-up capacity and marshalling capacity, etc.Secondly, by analyzing the interval time of train arriving from all the directions linking up the marshalling station, assessing the time standards of all kinds of technical operations and collecting different technical information, proper reserve capacities of equipments can be made by calculating different technical operation criteria on the basis of queuing theory. The reserve capacity can make sure the train can arrive at marshalling station in the rush hour with no delay and ensure the daily operation organization well.Lastly, capacity coordination of Guiyang south marshalling station is analyzed as an example. The paper researches the coordination relations and degree among sub-systems. The paper researches the train arrival regulation, especially in the rush hour, calculates correlative capacities and analyzes the coordination degrees. To achieve the best operation effect, capacity coordination among sub-systems and capacity coordination between marshalling station and railway line should be made by reinforcing weak segments and adopting some feasible measures, which plays a guiding role on the construction and reconstruction of railway stations and railway tracks.
