List the steps for recovering a full service brake application.

The correct answer provides a clear and systematic approach to recovering from a full service brake application in a train control environment. This procedure ensures that the train can resume operation safely after a braking event.

Firstly, moving the speed selector to "stop" halts any unwanted movement and prepares the system for the next steps. Following this, toggling the automatic brake to full engages the braking system fully, ensuring that any residual braking forces are neutralized before moving to the next state.

Pressing the vigilance toggle is crucial because it acts as a safety feature that ensures the operator is alert and actively controlling the train. Finally, releasing the brakes properly allows the train to move again once all safety checks have been satisfied. This sequence of actions maximizes safety while ensuring adherence to operational protocols.

Other options provided do not follow the correct procedural protocol necessary for safely recovering from a full service brake application, which emphasizes the importance of using the right series of steps in train operation duties.
