早期,列车的交通控制系统(TCS)非常简单,主要包括本地信号操作员或列车乘务人员所作的操作决定。通讯主要通过电线杆链路发送。自20世纪70年代起,电线杆链路逐渐被光纤链路取代。
如今,列车交通是通过调度集中控制系统(CTC)管理的。远程办公室的操作员可以通过远程控制进行通讯。CTC办公室内有铁路线路的实物模型,能够描述特定区域内的列车位置。轨道计轴器能够检测到经过的不同列车。然后讯息会以电子方式发送至控制点,指示列车继续行进或停车。控制点通常由双控开关管理。双控制开关可以通过两种方式打开或关闭:一种是通过中央调度员操作,另一种是用控制杆或泵进行手动操作。
随着新技术的发展,CTC正在快速演变。卫星信号、微波和数据链路的使用等被纳入新的列车管理系统,而且世界各国都正在使用这些系统。Topic41CTCLanguagePoints1ExplanationofDifficultSentences1.Itconsistedmainlyofdecisionsmadebylocalsignaloperatorsormembersofthetraincrew.
