What advantage do route request buttons have over whistles?

Route request buttons provide a significant advantage as a more accurate form of communication compared to whistles. While whistles can convey basic signals and commands, they are subject to interpretation and can vary in sound based on the individual using them or environmental conditions.

Route request buttons, on the other hand, offer a standardized method of signaling that eliminates ambiguity. When a train operator uses a route request button, it sends a clear, precise signal that is universally understood within the operational framework. This reduces the possibility of miscommunication between train operators and crew members, which is crucial for ensuring safety and efficiency in railway operations.

This precision is especially important in high-traffic scenarios or complex route changes where clear communication is vital to prevent accidents or operational delays. Overall, the use of route request buttons greatly enhances clarity and reliability in signaling compared to the more subjective nature of whistle signals.
