Train Structure and Maintenance Window Setting Strategies for 200 km/h Mixed Passenger and Freight Railway Lines
摘要
Abstract
The train structure and maintenance window are technical strategies adopted to facilitate the implementation of the train operation plan and infrastructure maintenance for 200 km/h mixed passenger and freight railway lines.They serve as the cornerstone for formulating transportation organization schemes,playing a pivotal role in railway traffic safety,transportation efficiency,and capacity.This paper firstly introduced train structure characteristics by describing train types,speed-density-weight,train operation organization modes,and train tracking modes.Additionally,it delineated maintenance window features by incorporating window types,window durations,and window time period elements.Furthermore,the paper systematically reviewed the current status of train structure and maintenance window on typical 200 km/h mixed passenger and freight railway lines in China(including the Nanchang-Fuzhou Railway,Qingdao-Yancheng Railway,Shanghai-Chengdu Railway from Liangwu to Chengdudong Station,Lanzhou-Chongqing Railway,Dazhou-Chengdu Railway,and Lanzhou-Urumqi High Speed Railway),and extracted their characteristics.Finally,inspired by the typical cases and considering 200 km/h mixed passenger and freight railway line characteristics and development trends,six train structure strategies and five maintenance window strategies were proposed.Considering the interplay between train structures and maintenance windows,eight synergistic train structure and maintenance window setting strategies were proposed.Each strategy's characteristics and applicable conditions were analyzed to provide a reference for decision-making regarding the setting strategies of train structure and maintenance window for newly constructed or reconstructed 200 km/h mixed passenger and freight railway lines.关键词
