在枢纽内,由于小运转列车、市郊列车多,列车密度大,以及各条干线间列车的相互交叉干扰,随着运量的增长,有的区间通过能力已不能适应,成为复线区间通过能力的控制地段。如我局××枢纽,地处三条干线的汇合点,如图1。除丙方向为单线外,其余均为8 min 间 In the hub, due to the small trains, suburban trains, train density, and inter-rail interference between the various trunk lines, as the volume of traffic growth, some of the interval capacity has been unable to adapt to become the second line capacity through Control lots. Such as my bureau × × hub, is located at the convergence of the three main lines, shown in Figure 1. In addition to the direction of C for the single line, the rest are 8 min between
