客运专线的合理站间距离

客运专线,尤其是高速客运专线．一般都是双线自动闭塞线路．区间平图通过能力与站间距离关系不大,车站的设置主要取决于客运的需要。但同一线路上如果既运行高速列车，又运行速度相对较低的普通跨线列车，则区段内高速列车必然要越行普通跨线列车．此时．同一区间内高速列车与普通跨线列车运行时间之差，将决定非平图区间通过能力的大小。

rational distances between stations of passenger special lines

Since, the passenger special lines, especially high speed ones, usually are double track railway with automatic block system, the carrying capacity of parallel train graph has little relation to the distances between stations. The setting of stations is mainly determined by the need of passenger transpod. But if the high-speed trains are operated along the same line with relative low-speed off-line trains, the highspeed trains must overtake the off-line ones. Here, the carrying capacity of parallel train graph is mainly determined by the time differences between the high-speed trains and the offline ones in the same interval But the traveling speed of the off- line trains will be reduced if the stations are set too many, and the high-speed trains overtake the offline ones too frequently for the sake of a higher carrying capacity of non parallel train graph. The rational distances between statiens of the passenger special lines are a range of distance of stations which must keep a certain carrying capacity of non parallel train graph as well as keep the traveling speed of off-line trains above the specified level.
