What should be displayed when the assisting train is seen or heard approaching?

• A. A lighted fusee
• B. A white flag
• C. A lantern
• D. A whistle

Answer: (A)

When flag protection is in effect and an assisting train is approaching, the signal required is a lighted fusee. This creates a highly visible warning for the crew of the stationary train, letting them know an approaching train is near and that they should maintain or establish proper protection. A white flag or lantern is not the designated signal for this situation, and a whistle is only audible and does not provide the necessary visual warning. The fusee ensures the approaching train is clearly marked, improving safety for both trains.
