The display of a yellow-red flag at a distance is specifically designed to alert train personnel to prepare for a stop due to the presence of men or equipment on or near the tracks. This signal is crucial for maintaining safety in areas where work crews might be present, as it warns trains to approach with caution and be ready to halt if necessary.

This use of the yellow-red flag emphasizes the importance of vigilance by train operators, ensuring they can stop safely to avoid any accidents or injuries to workers and to safeguard equipment on the tracks. The clarity of this signal is integral to safe train operations, especially in work zones or other areas where normal operations may be interrupted.
