When a Hot Box defect alarm is received, what should the crew do?

• A. Ignore the alarm and continue
• B. Stop the train to inspect
• C. Proceed to the next station
• D. Signal the next train

Answer: (B)

When a Hot Box defect alarm is received, the crew should stop the train to inspect. This action is critical because a Hot Box defect indicates that there may be excessive heat related to the bearings of one or more of the train's wheels, which can lead to significant mechanical failure or derailment if not addressed promptly. Stopping the train allows the crew to safely inspect the affected areas, assess the situation for potential damage, and take necessary action to ensure the safety of the train, its cargo, and any individuals nearby. Ignoring the alarm or proceeding without inspection would put everyone at risk, and while signaling the next train may be a part of emergency communication, it does not address the immediate need for inspection related to the detected defect.
