What alternative device may be used to indicate the rear of the train if the rear headlight is not illuminated?

• A. Illuminated marking device
• B. Flashing beacon
• C. Horn signal
• D. Reflective tape

Answer: (A)

When the rear headlight isn’t illuminated, the train must still clearly indicate its end for safety. An illuminated marking device is designed specifically to mark the rear of the train, providing a bright, visible cue that the train ends. This ensures following trains and yard personnel can recognize the rear even in darkness or poor visibility, meeting the requirement to indicate the end of the train. Other options don’t reliably serve that purpose: a flashing beacon isn’t the standard substitute for marking the rear end, a horn signal doesn’t indicate the train’s end position, and reflective tape alone may not be sufficiently visible in low light or from a distance.
