When is adjacent controlled track on-track safety not required for roadway workers?

Adjacent controlled track on-track safety is not required for roadway workers when all workers are positioned on the side of the occupied track that has no adjacent track or is equipped with an inter-track barrier. This is due to the fact that the inter-track barrier effectively provides a physical separation from the adjacent tracks, thus minimizing the risk of injury from train movements on those tracks.

When roadway workers are fully separated from an adjacent track, safety protocols can be adjusted appropriately, reducing the necessity for stringent on-track safety measures that would otherwise be required if there were potential hazards from the adjacent controlled track. This allows workers to focus on their tasks without the added concern for safety protocols regarding adjacent tracks, as the barriers are there for their protection.

In this scenario, the safety of the workers is ensured through the physical infrastructure in place, which does not necessitate constant on-track safety measures as it would in other situations.
