The sound of the train whistle is not just a simple noise on the railway; it is a special language, with each whistle conveying unique messages and meanings.
One of the important functions of the train whistle is to facilitate communication during operation. When a train is about to arrive at a station, the whistle sounds to signal passengers on board to prepare for disembarkation and reminds ground staff to be ready to receive the train.
To ensure safety on the railway, the train whistle serves as a warning.
Simultaneously, the whistle also reminds passengers and people on the platform to stay safe, advising them not to cross safety barriers. This is an effective way to maintain order and safety during the boarding and disembarking of passengers.
To ensure safety on the railway, the train whistle plays the role of a warning, especially when trains pass through intersections with roadways or when pedestrians appear on the track. The train must blow the whistle to alert pedestrians and vehicles near the track to move away from the dangerous area. When traveling over a bridge, the whistle also serves to signal pedestrians on the bridge and vehicles below, ensuring safety for everyone in the vicinity.
Different whistle combinations carry special meanings.
The train whistle is not just a single sound but has clear regulations regarding timing and type of whistle. A long sound typically lasts for 3 seconds, while a short sound lasts for 1 second, with a 1-second interval between them. Different combinations of whistles convey specific meanings, helping trains communicate and notify other vehicles effectively:
- One long, three short: This is an emergency alarm signal indicating a dangerous situation or the need for urgent rescue.
- Two short, one long: A signal to indicate that the train is preparing to enter or leave a section of track.
- Long sound: A signal for departure or to continue the journey.
- Two long sounds: A signal to return.
- Three long sounds: A recall signal.
- One long, one short: A steam signal.
- Two short: A signal for assistance or when the train is slipping.
- Three short: A signal to tighten the handbrake.
- Continuous short sound: An emergency stop signal.
Whistle codes are clearly defined, and each sound serves as a communication command to ensure smooth and safe operations.
The railway industry is currently striving to reduce whistle sounds in urban areas to avoid disturbing residents.
Previously, train whistles were also used when trains passed through residential areas to alert nearby residents and vehicles to be cautious. However, with modern and more enclosed railway systems, the use of whistles in densely populated areas has gradually become unnecessary and even disruptive to residents. The railway industry is currently working to reduce whistle sounds in urban areas to improve the quality of life for residents while balancing traffic safety and community interests.
As the railway system becomes increasingly modern and employs advanced technology, the role of the train whistle may continue to evolve to align with safety standards and social benefits. Nevertheless, the train whistle retains its value as an indispensable part of railway culture and technology, serving as a vibrant reminder of the importance of safety and the connection between humans and technology on every train journey.
