On a track signaled for movement in only one direction, which statement is true about operating in the opposite direction?

• A. Signal indication does not authorize opposite-direction movement
• B. Signal indication will authorize traffic in either direction
• C. Verbal permission is required for opposite-direction movement
• D. A Form D line 2 is required for opposite-direction movement

Answer: (A)

Signals that control movement are directional. When a track is signaled for movement in only one direction, that signal provides protection only for traffic going in that direction. Moving in the opposite direction is not authorized by that signal, so you would need separate authorization before proceeding. That’s why the statement that the signal indication does not authorize opposite-direction movement is the correct one. Verbal permission or a different protection method might be required in practice, but the signal itself does not authorize opposite-direction movement.
