On most modern railways, detection of the train’s position on the line and signal changing are done automatically and colored-light signals have largely taken the place of mechanical ones.
The light signals usually mean:
Green: proceed at line speed.
Yellow: warning-the next signal is at red.
Red: stop.
Railway signaling differs from the traffic lights used on roads in that trains cannot stop quickly; for example, a train traveling at 160 km/h (100 mile/h) would need several kilometers to stop. Therefore on a railway, train need to be given advanced warning of a red stop signal so that they can slow down to a speed where they can stop quickly (a yellow signal). Put another way, yellow signals usually do not indicate an impending change to a red signal at the same location. Rather, a yellow signal gives a train advance warning that the following signal will be red.
To achieve this, the railway is divided into “blocks”, where blocks are stretches of track be

在多数现代铁路, 火车的位置的侦查在线和信号改变自动地完成并且上色光信号主要代替机械那些。 光信号通常手段: 绿色: 进行在生产线速度。 黄色: 警告这下个信号是在红色。 红色: 中止。 铁路信号与红绿灯不同被使用在路由于训练无法迅速停止; 例如, 火车旅行在160 km/h (100 mile/h) 会需要几公里停止。所以在铁路, 火车需要被给一个红色停车标志的事前警告以便他们能减速对他们能迅速停止的速度(一个黄色信号)。投入其它方式, 黄色信号通常不表明对一个红色信号的紧急变动在同样地点。相反, 一个黄色信号给火车事前警告, 以下信号将是红色的。 达到这, 铁路被划分成"块", 块是舒展轨道在二个信号之间的地方。火车自动地被查出当他们进入块, 由什么完成为人所知当"轨道电路" 。 当计算块的大小和因此间距在信号之间, 下列必须被认为: 生产线速度(最大速度火车被允许旅行); 梯度(补尝协助或否则能减速); 看见(司机的能力看信号); 反应时间(的driver).The 轨道在或者块的末端电子被绝缘, 和在块之内小电流通行证虽则轨道。当火车通过信号和进入块、金属火车短路的轮子和轨潮流, 导致一个中转协会以轨道电路对本身成为丧气。 当中转丧气, 火车自动地通过了轮从绿色对红色的信号, 信号在那一个之后自动地转动黄色, 并且信号在那一个之后可能依然是绿色。
