Which of the following actions is the best description of when to use red fusees and flags at the start of a duty?

• A. Place six red fusees and one red flag on the lead locomotive, shoving platforms, and occupied caboose.
• B. Place red flags only on the engine and caboose.
• C. Use white lights instead of fusees at all times.
• D. Keep all warning devices off until the train moves.

Answer: (A)

Establishing protection for a movement or job on and around the tracks is the key idea. Red fusees and a red flag are the standard signals used to alert others that a train or equipment is about to move and to mark the protected area. The best description is to place six red fusees and one red flag on the lead locomotive, shoving platforms, and the occupied caboose. This arrangement creates a clear boundary of protection around all the involved equipment and is visible from multiple directions, so approaching trains or workers know to proceed with caution or stop. Placing them only on the engine and caboose wouldn’t fully protect the shove platforms, which are part of the movement and need markers as well. Using white lights instead of fusees isn’t appropriate here because fusees provide the standard red warning signal required for on-track protection. Keeping all warning devices off until the train moves would remove essential protection and safety.
