Emergency alarm boxes are primarily designed for what purpose?

Emergency alarm boxes are primarily designed to manage emergencies. These boxes serve as essential safety devices that allow personnel and passengers to quickly report incidents or situations that pose a threat to safety, such as accidents, medical emergencies, or other urgent situations requiring an immediate response. By providing a direct means of communication to emergency services and other relevant authorities, these devices play a crucial role in ensuring prompt assistance and minimizing the impact of emergencies on passengers and operations.

The other options do not align with the primary function of emergency alarm boxes. They are not intended for signaling maintenance issues, notifying traffic control regarding train movements, or communicating train schedules, which serve different purposes within railroad operations. The focus of the emergency alarm boxes is solely on managing critical safety situations, reinforcing their key role in the overall safety protocols of train operations.
