What does the displayed aspect signify when it instructs to stop, operate stop release, then proceed within vision?

The display that instructs to stop, operate stop release, then proceed within vision signifies that the train operator must first bring the train to a complete stop. After stopping, they are required to evaluate the situation ahead to determine if it is safe to continue. This procedure ensures that the operator has the opportunity to assess conditions for potential obstructions or other factors that could affect train safety before proceeding.

This instruction emphasizes caution and the importance of visibility in the decision-making process. By mandating a complete stop and an evaluation, it ensures that any imminent dangers or signals can be correctly acknowledged and addressed before the train moves forward. This is particularly crucial in situations where track conditions or operations may be unpredictable, necessitating a careful assessment before proceeding.
