What must be done at a Working Limits Stop Sign?

At a Working Limits Stop Sign, the proper protocol is to stop and then receive permission to proceed. This procedure is crucial for safety and operational efficiency within railway operations. The stop sign indicates that the train crew must halt their train to ensure that the area is clear from any blockages, maintenance work, or other activities that could pose hazards. Once stopped, the crew must communicate with the appropriate personnel or control center to confirm that it is safe to continue. This ensures that all safety measures are in place, minimizing the risk of accidents and allowing for proper coordination of train movements in areas where activities are taking place. This process is essential in maintaining a safe working environment alongside the rail lines.
