What is the function of a "Flagger" in a railway work zone?

A Flagger plays a crucial role in ensuring safety and proper traffic management in railway work zones. The primary function of a Flagger is to provide visual signals that direct both train traffic and workers in and around the work area. This involves using flags, lights, or other signaling devices to indicate when and where trains can safely pass through or around the work zone, thereby preventing accidents and ensuring that work can proceed without interruption.

The responsibilities of the Flagger are critical because railways have specific operational protocols that must be followed to maintain safety for both workers and train operations. By directing the flow of train traffic, the Flagger helps to establish a safe environment for construction or maintenance workers, reducing the risk of incidents. In contrast, other roles, such as cleaning debris or monitoring productivity, do not directly contribute to this essential function of traffic management within a work zone.
