What must a crew do before initiating movement on a main track when they receive a mechanically issued track warrant?

• A. verify the designated limits and any conditions of track warrants that convey authority with the dispatcher
• B. verify the OK time shown on the warrant
• C. log the movement with supervisor
• D. request an additional copy from the dispatcher

Answer: (A)

Before moving on a main track, the crew must verify the designated limits and any conditions of the track warrant with the dispatcher. The warrant defines the exact block of track you’re authorized to occupy and any restrictions that apply—such as speed limits, time windows, or other instructions. Verifying these details ensures you act within the authority granted and comply with all conditions, reducing the risk of conflicting movements or rule violations. Because the warrant is mechanically issued, you’re relying on a written document that must be checked against what you’re about to do; confirming the limits and conditions before departure makes sure your understanding matches the dispatcher’s authority. Other steps like checking only the OK time, logging with a supervisor, or requesting another copy don’t establish the actual movement authority and aren’t substitutes for this verification.
