Abstract

Different from the general calculation of the section passing capacity, evaluating the capacity of the block post where multiple lines meet in the hub area is a com-plex task, because the influence of the speed limit of lateral turnout, tracking interval of rail lines in all directions and actual train timetable of each rail line on the capacity of the block post should be taken into account. On the basis of summarizing the existing research on capacity calculation and its influencing factors, we propose a capacity evaluation method of the block post in the hub area, taking Liwan block post as an example. This method mainly supplements and improves the assessment of the passing capacity of the block post from three aspects, that is evaluating the time horizon of each rail line, determining the tracking interval of each rail line and analyzing the influence of passing through the lateral turnout on the tracking interval. The case study shows that the method proposed in this paper can comprehensively consider many problems involved in the calculation of the passing capacity of the block post.
