What is the meaning of the end time in a track warrant?

• A. End time defines the period during which the authority is valid.
• B. It is the time the train must finish its mission.
• C. Indicates maintenance closure.
• D. Time when crew must check in.

Answer: (A)

The end time on a track warrant marks when the authority to occupy a defined track segment expires. It creates a safe, bounded window for the train to operate under that warrant. After that moment, the train must not continue on the section unless a new or extended warrant is issued and accepted. This ensures there’s a clear limit to occupancy so conflicts with other trains are avoided. The other ideas—finishing a mission, maintenance closure, or crew check-in—are unrelated to how long the track warrant remains valid.
