At Which Station the Low-speed Train Should Be shunted into the Subsidiary Main Track on the Mixed Traffic Line?

초록

A subsidiary main track for passenger station is a low-speed track section distinct from a through route such as a main track. It is parallel to a through track and connected to it at both ends by switches. It allows for fast, high priority trains to pass slower or lower priority trains going the same direction. In this paper we first describe the minimum headway between trains using the concept of blocking time in a block section, which depends on block systems, signaling system and safety technology. And then a stepwise process is presented to select a location, at which it is suitable to shun a low-speed train into the subsidiary track for a given train-traffic pattern. This process is tested using train traffic simulation program RailSys® with sample track data, which are surveyed from track geometry based on the to-be constructed line.
