What information must a crew member provide when reporting clear of track warrant limits?

When a crew member reports clear of track warrant limits, it is essential to provide specific information that confirms their status and maintains safety and communication protocols on the railway. The correct information to provide in this situation includes identification details and the track warrant number. This ensures that the dispatcher or control center can verify the location and status of the train, confirming that it has safely exited the designated track warrant limits.

Providing identification helps to ensure accountability and traceability, while the track warrant number links the report to the specific authorization granted for that section of track. This is critical for maintaining optimal safety procedures and ensuring that the railway system operates efficiently without overlap or confusion of train movements.

The other options, while potentially relevant in different contexts, do not directly pertain to the requirements for reporting clear of track warrant limits. Knowing the track signs encountered or the number of passengers is not mandated in this specific report, nor is personal information like a driver's license number necessary for railway operations.
