Why do trains sound horns?
Train horns are required by federal law to be blown at all public crossings, at all hours of the day for the protection and safety of motorists and pedestrians using those crossings. Crossings with gates and lights are not exempt from the regulation. Only crossings that have met Federal Railroad Administration (FRA) criteria for a Quiet Zone do not require the horn to be blown. The federal regulation governing horn use was changed in June 2005 and now requires trains to blow the horn 15 to 20 seconds for each and every public crossing. This new federal regulation overrides all of the previous state laws that also required the horn to be blown at all public crossings. BNSF has produced a DVD that helps explain the new horn rule to our train crews and the communities we serve. You can watch that DVD online by clicking on the attached link.
