If a train overruns an authority, which actions are required?

• A. Notify the train dispatcher.
• B. Provide warning against approaching trains.
• C. Both notify the dispatcher and provide warning.
• D. Do nothing until instructed.

Answer: (C)

Overrunning an authority creates a safety risk because the protected movement is no longer in effect, so immediate steps are needed to re-establish protection. The correct actions are to notify the train dispatcher so they can reassess protection and issue new instructions, and to provide a warning to approaching trains so they can stop or proceed with caution. These two actions work together to keep all trains informed and protected: the dispatcher knows the situation and can coordinate the proper authority, while following trains receive a warning and can take appropriate action. Doing only one part leaves trains unaware or the track unprotected, which can lead to a collision or unsafe conditions.
