railway signalling

Railway signalling is a system that manages train movements to ensure safety and efficiency. It uses signals, signs, and track-based devices to communicate instructions to train drivers, indicating when to stop, proceed, or slow down. Signals can be visual lights, electronic displays, or track circuitry, and they help maintain safe distances between trains. Central control centers monitor train locations and coordinate movements, preventing collisions and delays. Overall, signalling ensures that trains run smoothly on the network by providing clear, reliable instructions, much like traffic signals for road vehicles.
