BNSF Dispatcher Trainee Practice Exam

The correct answer is the track warrant number because it is a specific identifier assigned to the track warrant that confirms the authority granted for train movements. When a crew member is confirming the release of a track warrant, they must reference this unique number to ensure that the correct authority is being utilized for operations. The track warrant number serves as a verification tool that links the crew's actions to the specific instructions outlined in the warrant.

Other options do not apply in this context. Yard limits authority is related to rules that apply within designated areas but does not confirm the release of a track warrant. Work between authority refers to instructions for movements on segments of track but, again, is not tied to the formal release of a track warrant. Movement authority is a broader term and can refer to different forms of authority granted for various operations, but it does not provide the specific confirmation needed for track warrant release. Thus, the track warrant number is crucial for maintaining accuracy and safety when addressing train movements.
