rail signaling technologies

Rail signaling technologies ensure trains run safely and efficiently by conveying information to train operators. They use a combination of fixed signals, like lights or displays along the track, and advanced systems such as track circuits, which detect train positions. Modern technologies include electronic signals, computer-based interlockings, and train control systems like Positive Train Control (PTC), which can automatically slow or stop trains to prevent accidents. These systems coordinate train movements, manage traffic flow, and ensure safe distances are maintained, all helping to prevent collisions and collisions, and improve overall rail network reliability.
