What should an employee do when notified of malfunctioning automatic warning devices?

When an employee is notified of malfunctioning automatic warning devices, sounding the whistle signal is an important safety measure. This action serves as a warning to others and helps ensure the safety of both the train crew and individuals who may be near the tracks. The sound of the whistle alerts nearby pedestrians and vehicles of the train's approach, compensating for the malfunctioning warning devices.

In circumstances where automatic warnings are not functioning, the responsibility falls on the train crew to take proactive measures to prevent accidents. Whistle signals are a conventional and effective means of communication in rail safety protocols and are crucial when standard warning systems fail. The employee must prioritize safety over any prohibitions regarding whistle use, especially when the functionality of other warning systems is compromised.
