What is the primary role of a flagman?

The primary role of a flagman is to restrict and direct the movement of trains. This responsibility is critical in maintaining the safety of both train operations and roadway workers. The flagman serves as a visual signal to trains, indicating when it is safe or necessary to slow down, stop, or proceed. This is essential in areas where maintenance or construction activities are taking place, as it helps to minimize the risk of accidents and ensures the safety of all personnel in the vicinity. Proper communication and signaling from a flagman are vital to coordinate activities on the tracks, ensuring a safe working environment for everyone involved.
