Quiet Zone Studies

The establishment of a Quiet Zone would restrict the routine use of train horns at public crossings within the designated area. Federal regulations mandate that locomotive horns must begin sounding 15–20 seconds before entering public rail grade crossings, no more than one-quarter mile in advance. However, communities can opt for Quiet Zones to enhance the quality of life for residents while still adhering to safety standards.
