What is the maximum speed defined as Slow Speed?

The correct answer defines Slow Speed as 15 MPH. In the context of railway operations, Slow Speed is important for ensuring safety in various situations such as work zones, passing through urban areas, or negotiating curves and switches.

Operating at this maximum speed allows for increased control of the train, giving crew members the ability to respond promptly to any hazards or obstacles that may arise on or near the tracks. It is crucial for maintaining safety in environments where the risk of accidents might be higher.

The other options indicate higher speeds that do not align with the standardized definition of Slow Speed within safety regulations. Such definitions are essential for implementing consistent protocols across railway systems to ensure the well-being of both the train crew and other individuals in the vicinity of rail operations.
