Which box provides either MW or non-directional (work between) track warrant authority to occupy the main track?

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

Answer: (C)

In track warrant control, the box that covers occupancy of the main track for MW (main line) or for non-directional work between two points is the one designated to authorize that specific type of authority. This box is used when the crew needs to occupy the main track regardless of direction, typically to perform work between two points or to operate under main-line authority without a fixed direction.

That’s why this box is the correct choice: it explicitly provides MW or non-directional (work between) authority to occupy the main track. Other boxes on the form are intended for different kinds of authority (such as directional main-track occupancy or other track restrictions), so they don’t meet the requirement described in the question.
