The assisting train must operate from that location to the disabled train?

• A. Form D line 2
• B. Form D line 5
• C. Form D line 9
• D. Form D line 8

Answer: (C)

Form D governs how an assisting train is cleared to move a disabled train. The line chosen on that form fixes the starting point of the assisting movement and the path toward the disabled train, so everyone knows exactly where the helper begins and how it will approach. Selecting the line that directs the assisting train to operate from that location to the disabled train sets up a defined, protected approach: the crew can establish communication, apply and control brakes, and coordinate coupling or movement with the disabled train safely from a known starting point. Using a different starting point would alter the protection and coordination required, potentially creating confusion or unsafe conditions.
