What is the purpose of Rule 410?

The purpose of Rule 410 is to control the speed of trains when there are no fixed automatic block signals present. This rule ensures that trains operate within safe speed limits in areas where signaling might not provide visual guidance. By maintaining appropriate speeds, the risk of accidents, collisions, or derailments can be minimized, especially in places where traditional signaling could be compromised or is not operational.

This aspect of train operation is critical to maintaining safety standards across the network, especially in regions with varying track conditions or even in areas dealing with temporary restrictions due to track maintenance or construction. The focus of Rule 410 is on ensuring that all trains navigate safely regardless of potential signal limitations.
