While under a YARD INDICATION signal, what is the operator allowed to do?

When an operator is under a YARD INDICATION signal, it indicates that the train is allowed to proceed but with caution. This is critical because although the train is permitted to move forward, the operator must be vigilant for potential hazards or changes in track conditions. Operating at reduced speed under such a signal allows the crew to maintain awareness of their surroundings and react appropriately to any signals, movements, or other events that may require a quick response.

This careful approach ensures safety and compliance with the operational protocols in the yard, where activities may be complex due to the interaction of multiple trains and equipment. The allowance to proceed without stopping, as long as caution is exercised, is intended to facilitate efficient movement within the yard while maintaining safety standards.
