A Train Or Track Car Must Not Be Operated Without A?

• A. Red Flag, White Light, At Least 6 Fusees
• B. Blue Flag And Lantern
• C. A Token And Key
• D. A Whistle

Answer: (A)

Flag protection for workers on or near the track requires a specific signaling setup to prevent trains from entering an active work area. The standard is to display a red flag or red light to signal trains to stop, use a white light for visibility at night, and place at least six fusees to mark the protected limits and give trains adequate warning and stopping distance. This combination uniquely provides the guaranteed protection crews rely on. Other signaling like blue flags and lanterns relate to different protection methods and do not meet this requirement in the same way. A token and key are related to authority in some signaling systems and aren’t substitutes for flag protection, and a whistle alone does not establish the necessary protection signals. Hence, the required setup is a red flag, a white light, and at least six fusees.
