rail signaling

Rail signaling is a system that manages train movements to ensure safety and efficiency. It uses signals—lights or signs—placed along tracks to communicate whether a train can proceed, slow down, or stop. These signals are controlled manually or automatically, based on the position and speed of trains, track conditions, and schedule needs. Modern systems often include electronic and automated components that monitor train locations and relay real-time instructions. By guiding trains smoothly and preventing collisions, rail signaling helps maintain a consistent, safe, and reliable railway operation.
