Where Rule 261 is in effect, a train must not make a reverse movement -beyond the limits- of the block without?

• A. Form D line 2 authority, as prescribed by non-signaled DCS rules.
• B. Verbal permission of the Dispatcher
• C. Written permit from the interlocking operator.
• D. Radio confirmation from the lead engineer.

Answer: (B)

Rule 261 governs movement beyond the limits of a block. When this rule is in effect, a train cannot reverse beyond block limits unless the Dispatcher formally authorizes it by giving verbal permission. The Dispatcher has the authority to authorize exceptions to block boundaries to prevent conflicts and collisions and to coordinate train movements safely. This permission is typically conveyed verbally, such as by radio or phone. The other options don’t fit because they involve different authorities or contexts: Form D line 2 applies to non-signaled DCS situations, a written permit from an interlocking operator is for interlocking-specific moves, and a radio confirmation from the lead engineer does not grant the dispatcher’s required authority.
