In response to a legislative mandate, FRA has issued a Final Rule on the Use of Locomotive Horns at Highway-Rail Grade Crossings. This final rule, which requires that locomotive horns be sounded as a warning to highway users at public highway-rail crossings, took effect on June 24, 2005. The final rule provides an opportunity, not available until now, for thousands of localities nationwide to mitigate the effects of train horn noise by establishing new "quiet zones." The rule also details actions communities with pre-existing "whistle bans" can take to preserve the quiet they have become accustomed to.
