If unable to obtain authority and it is necessary to foul or occupy a main track, what protection is required?

• A. Protection Must Be Provided In Both Directions
• B. Visual Signals Only
• C. Verbal Authorization Required
• D. No Protection

Answer: (A)

When you foul or occupy a main track without authority, you must provide protection in both directions. The main track is used by trains coming from either end, so safeguarding against approaching traffic from either direction is essential to prevent a collision. Visual signals alone aren’t reliable protection, and verbal authorization cannot substitute for active protection in this scenario. No protection would leave the fouling area exposed to oncoming trains. By ensuring protection in both directions, you create a clear, two-sided safeguard that trains will recognize and comply with, even without formal authority.
