南京东站第28至31道三部位设反坡调速系统快有三年时间了,有人问:三部位用石碴堆起的反坡段,其坡度能保持吗?线路安装了减速顶和加速顶,还有风管路,工务维修工作怎样?我可以告诉你:三年来,我们只对通过车辆比较多的第28、29道的反坡段四个钢轨接头处作过捣固,对这两股道的其它区段以及第30、31道都没有进行过捣固,至 Nanjing East Railway Station Road 28-31 on the 3rd part of the anti-speed control system is almost three years fast, someone asked: three parts stacked with ballast anti-slope section, the slope can maintain it?
