What speed must all movements be made within yard limits located in block signal territory?

Within yard limits located in block signal territory, all movements must be made at restricted speed. Restricted speed is defined as the maximum speed at which a train can safely operate under conditions that may require immediate stopping within half the range of vision or a distance of no more than 1,200 feet. This ensures the train can react to unexpected obstacles, such as other trains, equipment, or personnel within the yard.

In this context, operating at restricted speed allows for greater safety as it accommodates the reduced visibility and dynamic environment found in yard operations. Yard limits are areas where trains may be entering or departing from yards or sidings, and the potential for unexpected movements is high, making restricted speed essential for safe train handling. This speed allows for increased caution and flexibility in responding to any changes in the situation, minimizing risks associated with higher speeds.

Understanding this concept is crucial for maintaining safety and efficiency in train operations, particularly in complex yard settings where multiple movements can occur simultaneously.
