What must be done if any signal does not conform and is imperfectly displayed?

If any signal does not conform and is imperfectly displayed, it is essential to report the condition without delay. This immediate reporting is crucial because signals convey vital information about train movements, safety, and the operational status of the railway system. A malfunctioning or unclear signal can lead to hazardous situations, including potential accidents or misunderstandings among train crews.

By promptly notifying the appropriate personnel, measures can be taken to rectify the issue, ensuring that all trains are operating under the correct signals and maintaining safety protocols. Ignoring the signal condition or delaying its reporting could put the safety of passengers, crew, and railway operations at risk. Therefore, the emphasis on immediate communication reflects the priority given to safety and the maintenance of efficient train operations in the LIRR Operating Rule Book.
