既有双线提高旅客列车速度对起停附加时分及追踪列车间隔的影响

The Influences on Additional Starting/Stopping Time and Tracking Train Headways by Raising Running Speed ofPassenger Trains on Existing Double Railway Lines

将旅客列车速度提高到１４０～１６０ｋｍ／ｈ是铁路改善旅客运输质量、参与市场竞争的重要手段，是铁路面临的新课题。本文对既有双线自动闭塞区段提高旅客列车速度并相应提高货物列车速度后旅客列车起停附加时分及货物列车起停附加时分的变化进行了分析和讨论，进而对旅客列车提高速度后的列车追踪间隔时间Ｉ追、列车到达间隔时间Ｉ到、列车出发间隔时间Ｉ发和列车不停车通过车站间隔时间Ｉ通的变化情况进行了较为详细的分析。

To improve the service quality of railway passenger transportation and to meet the needs of market competition, the measure of raising running speed of passenger trains on existing double railway lines must be taken. In this paper,the changes of additional starting/stopping time on passenger trains and freight trains are discussed when the running speed of passenger trains is raised and the running speed of freight trains is also raised correspondently on existing double railway lines. The changes of the tracking train headways, the arriving tracking train headways, the starting tracking train headways and the station passing tracking train headways are also discussed.Finally, some useful conclusions are reached.
