In cases of communication failure, which Form D line may be used to authorize passage before the train arrives at the Stop Signal?

• A. Line 7
• B. Line 1
• C. Line 13
• D. Line 21

Answer: (C)

When communications fail, Form D is used to authorize a train to move under restricted conditions despite not having a normal signal clear. The line on Form D that is specifically designated to permit passing a Stop Signal before the train arrives at that signal is the one you choose for this situation. It’s purpose-built for allowing the train to continue past a Stop Signal while the crew follows the defined safety checks and restrictions so movement can continue without waiting for normal communications. The other lines on Form D cover different scenarios and do not authorize passing a Stop Signal prior to arrival, so they aren’t applicable here.
