In this video I will tell you about the principle of operation of automatic blocking on the railway, as well as about passing traffic lights, and actually about how trains keep their distance from each other and do not catch up with each other. Surely, standing somewhere on the stretch, you could notice that initially the traffic light is green, then a train passes and immediately after it passes, the red light comes on, after some time yellow, and then green again. This is exactly what we will talk about. If you liked this video - please subscribe to the channel and like it! In this way, you will support the development of the channel.
