What is the required action when a train encounters a Diverting Approach Sign?

When a train encounters a Diverting Approach Sign, the required action is to stop and then get permission to enter working limits. This sign typically indicates that the train must be prepared to divert from its expected route, and it serves as a warning that there may be track work or other conditions ahead that require a specific protocol to be followed.

By stopping, the engineer is able to assess the situation and ensure safe passage through the area. Seeking permission to enter working limits is crucial in ensuring that any maintenance activities or other trains in the area are accounted for, which aids in preventing accidents and maintaining safety standards. This action emphasizes the importance of communication and protocol compliance in railroad operations, underscoring the need for awareness and caution when navigating through potentially hazardous areas.
