What must be done after noticing a malfunction of the warning device in Rule 410 territory?

In Rule 410 territory, the procedure for a malfunctioning warning device prioritizes safety and operational protocol. When a warning device, such as a signal or any other safety-related indicator, is not functioning properly, the correct procedure is to report the malfunction immediately and then proceed at restricted speed. This approach is designed to ensure that train operations can continue safely while minimizing the risk of accidents or collisions due to unclear signals.

Proceeding at restricted speed allows the train crew to maintain control and be prepared to stop within half the range of vision. This is essential in situations where the malfunction may affect the train's ability to respond to other signals or conditions on the track.

Reporting the malfunction ensures that appropriate actions can be taken to fix the issue and maintain the safety of all operations on the line. By following this protocol, the crew adheres to safety regulations and fosters a culture of communication regarding safety issues.
