What should a train operator do if the train whistle becomes inoperative while en route?

If a train whistle becomes inoperative while en route, the train operator is required to stop immediately and contact the rail control center for further instructions. This procedure is vital for several reasons.

The train whistle serves as an important safety device that alerts people and other vehicles at crossings and along the track of the train's presence. Without the ability to signal using the whistle, the train operator cannot ensure the safety of both the passengers and individuals near the tracks. By stopping the train and notifying the rail control center, the operator ensures that the situation can be assessed and appropriate measures can be taken, which may include assessing the train's continued operation or arranging for a backup procedure to ensure safety.

Continuing to the next station without addressing the inoperative whistle could pose significant safety risks, while simply slowing down or alerting passengers doesn't mitigate the lack of signaling and could lead to dangerous situations. Therefore, contacting the rail control center enables a structured and safe response to the malfunction.
