Design of Train Group Operation Mode for Heavy-Haul Railways
摘要
Abstract
The train group operation mode serves as the foundation for group operations and directly influences both the efficiency of train group operation and the transport capacity of heavy-haul railways.To improve the efficiency of train group operations,this paper investigates methods for designing train group operation modes for heavy-haul railways.First,the concept of the train group operation mode is introduced,and it is clarified that it consists of the following elements:unit train type,quantity,and formation sequence.Based on this,typical train group operation modes are classified into three categories:pure conventional train groups,pure 10 000-ton train groups,and mixed groups of conventional trains and 10 000-ton trains.Furthermore,a comparison method for train group operation modes is proposed,with three key indicators:utilization rate of passing capacity,adaptability rate of transport capacity,and adaptability rate of power supply capacity.Finally,using the Shuohuang Railway as a case study,twelve candidate train group operation modes are proposed and compared.The results show that the operation mode of"three 10 000-ton train grouping"can fully utilize the transport capacity of the Shuohuang Railway under the constraints of transport demand and power supply capacity.关键词
