What should an operator do when On-Track Safety flagging is posted without work zone indication?

Operating according to the flagging posted and informing Control is the correct action because On-Track Safety flagging serves as a crucial indicator of potential hazards or conditions that require operators to adjust their behavior for safety. When such flagging is posted, it signifies that there may be an ongoing safety concern, even if specific work zone indications are not clearly delineated.

By adhering to the posted flagging, an operator acknowledges the signaling of precautionary measures, thus maintaining safety protocols designed to protect both the train crew and any personnel who might be working on or near the tracks. Additionally, notifying Control is essential because it allows for communication of potential concerns regarding the flagging, ensuring that all necessary parties are aware of the situation. This collaborative approach enhances overall situational awareness and operational safety.

In contrast, overlooking the flagging or failing to communicate with Control can lead to dangerous situations, as the operator might miss vital safety information that could affect their operational decisions.
