Which box grants a train directional track warrant authority to occupy the main track?

• A. Box 4
• B. Box 5
• C. Box 3
• D. Box 7

Answer: (C)

In Track Warrant Control, the authority to occupy the main track in a specific direction comes from the control point that has jurisdiction over entering that main-track segment for that direction. The box at that entry point is the one that issues the directional track warrant, and the train may occupy the main track only under that warrant’s protection and limits.

So, the correct box is the one that governs entry to the main track for the requested direction. It provides the required authorization to occupy the main track within the defined limits and protects against conflicts with other movements. The other boxes control different blocks, yards, or movements in the opposite direction, and they do not issue the warrant for this entry, so they do not provide the required authority. Without the warrant from the proper box, occupying the main track would be unsafe.
