What is the maximum speed for extra trains moving within yard limits?

The maximum speed for extra trains moving within yard limits is established at 15 miles per hour. This speed limit is crucial for ensuring the safety of both the train crew and any personnel or equipment that may be present in the yard area. Yard limits are typically zones where lower speeds are mandated to allow for increased caution, as trains may encounter switching movements, maintenance activities, and other hazards that are common in and around yard facilities.

By setting the speed limit at 15 miles per hour, the operating rules help to maintain a manageable pace for train movements, minimizing the potential for accidents or injuries. The presence of other trains, equipment, and workers necessitates a more controlled environment, thus the lower speed restriction specifically caters to these operational realities.

In contrast, other speed options like 10, 20, or 25 miles per hour may not properly reflect the safety considerations inherent to yard operations, where unpredictability is the norm, demanding a more conservative approach to train speed.
