What conditions must be met for Dispatchers to direct track cars to add additional line 2 authorities?

• A. New movements authorized within the limits.
• B. No new movements authorized and signals in Stop position.
• C. Only on certain dates.
• D. Once per shift.

Answer: (B)

In order for dispatchers to direct track cars to add additional line 2 authorities, the condition that no new movements are authorized and that signals are in a stop position is essential. This ensures the safety and integrity of the operation. If new movements were authorized or if signals were not in the stop position, there could be the potential for conflicts or accidents as track cars are integrated into the line.

When signals are in the stop position, it indicates that no trains should be moving in that section of track, allowing dispatchers to make changes or additions to line 2 authorities without the risk of interference from active movements. This condition helps maintain a safe control environment while enabling the dispatcher to manage track resources effectively.
