A train horn is a powerful air horn that serves as an audible warning device on electric and Diesel locomotives. The horn's primary purpose is to alert persons and animals to an oncoming train, especially when approaching a grade crossing. The horn is also used for acknowledging signals given by railroad employees, such as during switching operations.
The Florida East Coast Railway has fielded up to 20 complaints a week about louder train horns since it introduced 24 new General Electric locomotives in December. Initial testing showed the sound of the horns actually was a little lower than the old locomotives. But company officials ordered more in-depth tests with an acoustic expert.
