A track warrant is in effect until which statement is true?

• A. The crew member reports the train has cleared the limits or the track warrant is made void
• B. The track warrant number being released
• C. The limits being released
• D. The dispatcher issues a new track warrant.

Answer: (A)

Track warrants grant authority to move within a defined block and stay in effect until that authority is terminated. The termination happens when the train has cleared the limits or the warrant is explicitly voided. This ensures the block is released for other movements and that safety is maintained.

That’s why the best choice is the condition where the crew reports the train has cleared the limits or the track warrant is made void. The end isn’t determined simply by releasing the warrant number or by just releasing the limits in isolation—the formal end condition centers on clearance or explicit cancellation. Issuing a new warrant may change who has authority, but it doesn’t define the end of the existing one on its own.
