What must Extra trains be prepared to do while moving in Yard Limits?

When operating within Yard Limits, Extra trains are required to be prepared to stop within one half the range of vision. This rule is crucial for ensuring safety in the yard environment, where there are often unexpected movements, equipment, and personnel present. The limited range of visibility means that train crews must be vigilant and ready to react promptly to any obstacles or signals that may arise.

Understanding this requirement reinforces the need for caution and attentiveness in areas where the operations are unpredictable. In contrast, exceeding the speed limit, accelerating past hold points, or waiting for permission to proceed may not align with the expectations and safety protocols established for movements within Yard Limits.
