Question: 1 / 400
What function does Automatic Train Control (ATC) serve?
Allows automatic selection of train routes
Indicates a penalty brake application when speed is not reduced
Automatic Train Control (ATC) is a critical safety system used in train operations, primarily designed to ensure the safe movement of trains. One of its vital functions is to monitor train speed and enforce safe operational limits. When a train exceeds its maximum speed or fails to reduce speed as required, ATC initiates a penalty brake application. This means that the train will automatically apply the brakes to slow down or stop the train in order to prevent accidents caused by excessive speed.
While other functions such as route selection, passenger counting, or punctuality management may be related to train operations, they are not the primary responsibility of ATC. The system's main focus remains on safety, particularly in managing speed and braking to avoid risks associated with human error in train operation.
