What is "automatic train control"?
Automatic train control (ATC) is a system used in trains to manage and regulate the train's speed, ensuring it operates safely and efficiently. ATC continuously monitors the train's position and speed in relation to track signals and other trains. It can automatically adjust the train's speed or stop the train if it detects any potential danger, such as approaching a red signal or a restriction on the track. This system helps prevent accidents, enhances safety, and reduces the need for manual intervention, allowing for smoother and more reliable train operations.
Examples
Many modern railways employ automatic train control to prevent collisions and manage traffic flow.
