目前我国铁路大多数中间站未设牵出线,调车时需要占用正线、到发线。近年来列车密度逐年增加,使中间站的调车作业和安全生产难度加大。中间站一旦在调车作业中发生脱轨、冲突事故,很容易堵塞咽喉,造成行车中断,将对运输生产带来很大影响。故采取措施防止中间站调车脱轨、冲突事故的发生是当前的重点攻关课题。 At present, most of the railway stations in our country are not equipped with pull-out lines. Shunting needs to occupy the positive line and arrive at the line. In recent years, the train density increased year by year, so that the intermediate station shunting operations and production safety more difficult. Once the derailment and collision accidents occurred during the shunting operation of the intermediate station, it is easy to plug the throat and interrupt the traffic. This will greatly affect the transportation and production. Therefore, measures should be taken to prevent the derailment of shunting at the intermediate stations. The occurrence of conflicts is the key issue for the time being.
