Question

How do those lights on the train track turn on? Is there a system that senses the train or is there a certain HQ place that people control the lights?

Answer 1

Rail networks are monitored by head quarters who can see where trains are at all times.

But it’s just a trigger sensor on the rail line. At some distance away from the crossing, there is a sensor or button that flips when a train passed over it and triggers the warning lights to start.
