What is required before a crew can proceed after a receipt of a hot wheel defect alarm?

In the context of safety protocols for train operations, it is crucial for a crew to conduct a job briefing with the train dispatcher before proceeding after receiving a hot wheel defect alarm. This step ensures that all relevant information regarding the situation is shared and understood by the crew and the dispatcher. The briefing allows the crew to review the specific circumstances of the alarm, including any necessary actions, potential risks, and the overall status of the train. Communication between the crew and dispatcher is vital in maintaining safety standards and ensuring that appropriate measures are taken to address the defect before proceeding.

This procedure aligns with standard operating practices that prioritize thorough communication and assessment of the situation, ensuring that everyone involved is informed and prepared for any necessary actions.
