Track Car that is to be used for maintenance on a main track must be issued what to be on track?

• A. Form D line 2
• B. Form D line 3
• C. Form D line 4 OR line 5
• D. Form D line 1

Answer: (C)

When a track car is used for maintenance on the main track, it needs explicit authority to operate there. Form D is the document used to grant that authority, and its different lines specify the type of movement and the protections that apply. The line designated for maintenance-of-way equipment on the main track is the one that covers a track car doing work on the main line. Using that line ensures the movement is properly authorized and protected, with any required flagging or work protections in place. The other lines on Form D are for different kinds of movements (such as regular trains or other activities) and do not authorize a maintenance track car on the main track. That’s why the correct choice is the option that references the line for maintenance on the main track.
