What must the dispatcher confirm before granting permission for a reverse movement beyond a block in 261 territory?

In 261 territory, prior to granting permission for a reverse movement beyond a block, it is crucial for the dispatcher to confirm that all signals are in the Stop position. This requirement ensures that there are no conflicting movements or potential hazards in the area, providing a safe environment for the reverse movement to occur. By ensuring that all signals are set to Stop, the dispatcher is indicating that no trains should be moving on the tracks, allowing for a safe operation without the risk of an accident.

The safety protocol in rail operations prioritizes the need for clear communication and status awareness regarding signals to prevent mishaps. A reverse movement on occupied tracks could lead to serious incidents if other trains are present and signals do not appropriately indicate that the track is clear. Thus, confirming that all signals are in the Stop position is a critical step in maintaining operational safety.
