Forum Thread: Interesting Thing About How Railway Signal Works

In this video i wanted to show how the railway signal works. Sorry for a poor quality, this is my first video on youtube. Interesting thing. When train is approaching to the road crossing, signal immediately turns on. The secret is that there is a signal coming through the rails, and when train is near, it close this signal and siren starting work.
