英国铁路货运量比较小,而旅客列车次数很多。因此,线路标准对平顺度要求较高,以保证有较好的乘车舒适性。轨道必须勤加维修,但作业机械占用区间线路的时间则要尽可能减少。为此须改进维修方法,或者提高作业机械的工作效率,或者提高维修质量、延长维修周期。 British rail freight volume is relatively small, while the number of passenger trains a lot. Therefore, the line standard on the smoothness of the higher, in order to ensure better ride comfort. The track must be diligently repaired, but the operating machinery occupy the interval line time must be reduced as much as possible. To do this, it is necessary to improve the maintenance method, to improve the working efficiency of the working machine, to improve the quality of maintenance and to extend the maintenance cycle.
