The Transportation Organization Mode of Off-Line Train in Wuhan-Guangzhou High-Speed Railway

It has a great effect to capacity that a large amount of off-line trains running in Wuhan-Guangzhou High-Speed Railway (WGHR). The paper compares and analyzes the off-line train and in-line train’s proportion, speed, stop, and overtaking schedule plans. Taking Changsha South Station as an example, the paper analyzes the impact of off-line trains on station capacity. Due to the crossings, informing by the restriction turnout in the throat area, it takes a long time in throat area and tracks when receiving and departing off-line trains and then affects the station through capacity. The fixed time of off-line train makes the train intervals longer, and then impacts the section carrying capacity. Taking Changsha South-Hengyang East section as an example, it is found that when the proportion of off-line trains is about 65%, the capacity utilization rate is the lowest, only about 70%. Because the economic benefits of the off-line train is better and satisfies the company, and to is paper puts forward the suggestion that the transportation organization mode of off-line train should be single mode in peak hours and mixture mode in off-peak hours and the timetable of the off-line train remaining some problem can be optimized.
