Automated Train Control (ATC) is a system designed to manage train operations without direct human intervention. It uses technology to monitor train speed, track conditions, and signals, ensuring safe and efficient travel. ATC can automatically adjust a train's speed and apply brakes if necessary, reducing the risk of accidents. This system is often integrated with other technologies like Positive Train Control (PTC) and Centralized Traffic Control (CTC). By utilizing sensors and communication networks, ATC enhances the reliability of train services, minimizes delays, and improves overall safety for passengers and freight transport.
