What should the train crew do when they see a Working Limits Stop Sign without confirmation of no diversion?

When the train crew encounters a Working Limits Stop Sign, the appropriate action is to proceed prepared to stop at the sign. This is crucial for maintaining safety and complying with regulations related to work zones on the tracks. The stop sign indicates that the area ahead has specific work limits and potentially personnel or equipment present, which requires a cautious approach.

By preparing to stop, the crew ensures that they can respond appropriately to any unexpected conditions or obstacles that may arise as they approach the work zone. This action emphasizes the importance of situational awareness and the need to validate the condition of the tracks ahead before making any further decisions regarding speed or continuation of travel. This approach prioritizes safety, both for the crew and any workers who may be present on or near the tracks.
