What is the function of a whistle board?

The function of a whistle board is to notify the driver to sound the whistle. This is an important safety feature in rail operations, particularly in areas where trains may be approaching level crossings or entering populated areas where noise alerts are necessary. The whistle serves as an audible warning to pedestrians and vehicles, enhancing safety by making it clear that a train is approaching.

In the context of signaling systems, a whistle board acts as a reminder to the driver that they should sound the whistle at a designated point, ensuring that any potential hazards can be addressed proactively. Understanding the purpose of a whistle board is crucial for train operators to promote safety and awareness in their operating environment.
