The Dispatcher must then issue ______ to the assisting train?

• A. Form D line 1
• B. Form D line 9
• C. Form D line 5
• D. Form D line 7

Answer: (B)

When a train needs help, the Dispatcher uses Form D to convey the exact movement authority and protection requirements for the assisting train. The line on that form that communicates the action the assisting train must take—telling it to proceed and assist under the specified conditions—is the one issued to the assisting crew. That specific line is what formalizes the instruction for the assist operation, including any speed, routing, and protection details. Other lines on Form D cover identification, location, and general parameters, but the line that carries the operative instruction for the assisting train is the one the Dispatcher uses to authorize the assist.
