Which statement about track warrants and box 7 restrictions is true?

• A. It can be used for any direction movement
• B. It is restricted to train crews who advise they need to work in both directions
• C. It applies only to maintenance trains
• D. It is not associated with restrictions

Answer: (B)

Track warrants can include specific restrictions that control how and in which direction a movement may operate. Box 7 restrictions are used when a crew will be working in both directions, which requires extra protection because traffic could be approaching from either direction and the crew may need to back up or reverse direction. This is why the statement that box 7 restrictions apply only to crews who advise they need to work in both directions is the best answer. The other options aren’t correct because box 7 restrictions aren’t for any direction movement, aren’t limited to maintenance trains, and are indeed associated with directional restrictions.
