What describes Rule 410?

Rule 410 refers specifically to the operation of speed controlled trains in situations where fixed automatic block signals are not in use. This rule indicates that while these trains are allowed to operate, they do so under specific speed restrictions that are managed by the train's engineer or operator rather than relying on visual signals. Understanding this rule is crucial for ensuring safe operations, particularly in scenarios where traditional signaling systems are absent.

This acknowledgment of speed control without reliance on fixed signals is fundamental to maintaining operational safety and efficiency. It emphasizes the importance of having trained personnel to manage train speeds effectively in the absence of automated guidance.
