Which authority governs movement over specific tracks when signaling does not provide direct authorization?

• A. To grant permission to operate trains at any speed anywhere.
• B. To replace all signaling in the yard.
• C. To grant movement over specific tracks or blocks when signaling systems are not providing direct authority.
• D. To authorize mechanical inspection only.

Answer: (C)

When signals don’t give direct permission, there must be a responsible person who authorizes movement over the specific tracks or blocks. This designated authority reviews the current track occupancy and safety conditions and then issues movement over only those tracks or blocks that are approved. This keeps trains moving safely even when signaling isn’t providing a clear clearance.

So the best choice describes exactly that role: granting movement over particular tracks or blocks when the signaling system isn’t providing direct authority. It isn’t about unrestricted broad permission, replacing signaling in the yard, or merely authorizing inspections.
