What must be done if a train is advised of working limits behind them?

When a train is advised of working limits behind them, it is essential for the crew to obtain permission from the employee in charge. This procedure is critical for maintaining safety and coordination on the railway. Working limits generally indicate that maintenance or repair work is being conducted on the tracks behind the train, and there could be personnel or equipment in that area.

By securing permission, the train crew ensures that they are aware of any potential hazards and that it is safe for them to proceed. This measure helps to prevent accidents and ensures the safety of both the train crew and workers present on or near the tracks. It aligns with protocols regarding communication and operational control within the railroad system, ensuring that all parties are informed and that safe practices are upheld.
