What defines Yard Limits in Bi Di double line RVD territory?

In Bi Di double line RVD (Remote Varying Distance) territory, Yard Limits are defined specifically by signs that indicate boundaries within the yard. The End Yard Limit (YLB) Sign plays a crucial role in marking the limits of the yard during operations.

The End YLB Sign acts as a clear indication to train operators and maintenance personnel that they are entering or exiting a yard area. It is essential for maintaining safety and ensuring compliance with operational protocols in these specific territories. This sign is the definitive marker that signals the boundaries of the yard limits, helping to prevent unauthorized movements or activities beyond the designated areas.

While the SL Sign and other factors might contribute to overall situational awareness, they do not specifically define Yard Limits in the same way that the YLB Sign does. Therefore, the YLB Sign is the key element in determining where these limits are established.
