英语翻译
Though there is no train is occupying the overlap track circuit.This will give rise to two red signals showing behind a train while the train is in the overlap.
Automatic Train Protection
To adapt metro signaling to modern,electronic ATP,the overlaps are included into the block system.This is done by counting the block behind an occupied block as the overlap.So in a full fixed block ATP system,there will be two red signals and an unoccupied,or overlap block between trains to provide the full safe braking distance,as shown in Diagram 5.By the way,many ATP equipped system do not have visible lineside signals because the signal indication are transmitted directly to the driver’s cab console (cab signaling).
On a line equipped with ATP as shown above,each block carries an electronic speed code on top of its track circuit.If the train tries to enter a zero speed block or an occupied block,or if it enters a section at a speed higher than that authorized by the code,the

答案

虽然没有火车正在占领重叠轨道线路.当火车在重叠方面的时候,这将会引起在一列火车后面的二个红色的信号成绩.
自动的火车保护
为了要适应对现代人、电子的 ATP 作信号的地下铁道,重叠进入区段系统之内被包括.这藉由计算在一个被占领的区段后面的区段作为重叠被做.因此在完整的固定区段 ATP 系统,将会有二个红色的信号和空闲,或重叠在火车之间阻塞提供刹距离的完整的保险箱,如图表 5 所示.因为信号指示被直接地传送到驾驶员的出租汽车控制台 (出租汽车作信号) ,所以顺便一提,装备系统的许多 ATP 没有看得见的 lineside 信号.
在当做显示被装备 ATP 的一条线上上述的,每个区段在它的轨道线路的顶端上携带一个电子的速度密码.如果火车试着进入一个零的速度区段或者一个被占领的区段,或如果它以被密码授权的高于那的速度进入一个区段,那在-之上董事会电子学将会引起一个紧急的刹车申请.这是为维多利亚线被伦敦地下用的系统从 1968-首先完全自动者,乘客携带铁路.它用只有三个速度密码是一个简单的系统-常态,警告而且停止.建造的许多系统自从以它为基础以后但是进步已经被增加.
