The different losses of transport capacities are caused by crossing routes when the regional rail line takes different reentrant patterns in the middle switchback stations . Adaptability analysis is accomplished on Turn-back capacity of switchback stations according to different train routing mode .

轨道交通市域线在中间 折返站采取不同折返形式，由进路交叉 干扰所产生的能力损失不同，文章针对不同交路模式在中间折返站进行了能力适应性分析。

Finally this paper analyses the quantity of operating trains and the requirements of the switchback stations under the mixed running mode .

并以 上海 城市 轨道 交通 某 线路为例，分析了 不同编组混合运行条件下，车辆运用数量比较以及 折返站要求等问题。
