Blasts from the Rails: The Evolution of the Train Horn

 A train horn is a critical safety feature used on locomotives to alert pedestrians, animals, and vehicles of an approaching train. Its purpose is to prevent accidents at railroad crossings and along tracks where visibility might be limited. Train horns are powered by compressed air supplied by the locomotive’s air brake system. When activated, air is forced through a series of diaphragms within the horn, creating a loud, distinctive sound. The sound of a train horn is unmistakable and can be heard from a considerable distance, which is crucial for safety. In the United States, the Federal Railroad Administration (FRA) mandates the use of train horns at public highway-rail grade crossings. For more info click here #trainhorn
