What is the proper whistle signal to warn people near the platform edge?

The correct response involves using a specific signal, which is a series of short blasts, to warn individuals near the platform edge. This practice serves as an important safety measure, ensuring that pedestrians and individuals waiting on or near platforms are alerted to the train's approach. Using multiple short blasts conveys urgency and signals awareness of the proximity of the train, allowing people to prepare or move to a safe distance.

Typically, rail operators are trained to utilize these distinct whistle signals as gestures of communication both to promote safety and maintain an orderly environment at train stations. The specific number of short blasts is not defined as a singular standard, which allows flexibility in response to various situations, particularly in high-traffic areas or where additional caution is necessary.

Whistle signals are a standardized part of rail operations, and their proper usage can prevent accidents and ensure the safety of everyone involved.
