Who is described as a Flagger in railway operations?

• A. A device on the rail to indicate speed.
• B. A person who operates the dispatch center.
• C. An employee using a flag assigned to protect persons and equipment working on or near the tracks to ensure the safe passage of trains.
• D. A type of signal light.

Answer: (C)

A flagger is a worker assigned to protect people and equipment working on or near the tracks by using a flag (and sometimes a light or paddle) to signal trains. They control and coordinate train movements in the work zone, ensuring trains slow down or stop as needed and that the area is safe for personnel and equipment. This role is about on-site safety communication between track workers and train crews, not about fixed devices like speed indicators or signal lights, nor about centralized dispatch operations. In short, the flagger is the on-the-ground person who uses a flag to safeguard the passage of trains through or around a work area.
