市域(郊)铁路车辆选型及列车编组研究

Research on vehicle selection and train formation for urban region(suburban)railways

当前,我国市域(郊)铁路发展面临技术标准不明确、建设模式不清晰、运营效果不理想等问题,尤其是在车辆选型和列车编组方面尚未形成标准化体系。为解决上述问题,文章在分析国内市域(郊)铁路发展现状及客流情况的基础上,对其车辆选型和列车编组进行深入研究,提出市域(郊)铁路车辆选型宜从线路最高运行速度、乘坐舒适度、公交化水平、互联互通需求等多方面进行考虑,列车编组应结合线路客流量级、车辆技术成熟度和运营成本,选择“小编组、高密度”运营组织形式,并在此基础上以东南沿海某市域(郊)铁路线路为例,进行车辆选型及列车编组案例分析,以期为类似工程提供参考和借鉴。

The current development of urban region(suburban)railways in China is facing problems,such as unclear technical standards,unclear construction models,and unsatisfactory operational effects,especially in terms of vehicle selection and train formation,which have not yet formed a standardized system.To solve these problems,this article analyzes the current development status and passenger flow of domestic urban region(suburban)railways,conducts in-depth research on vehicle selection and train marshaling,and proposes that vehicle selection for urban region(suburban)railway should be considered from multiple aspects,such as the maximum operating speed,passenger riding comfort,public transportation level,and interoperability needs.Train formation selection should consider the passenger flow amount,the maturity of vehicle technology and operating costs,choosing a"short formation,high density"system for train organization.Based on this,a case study of vehicle selection and train formation should be conducted on a certain urban region(suburban)railway line in the southeast coast to provide reference for similar projects.
