Train Horns and Quiet Zones

  • Federal law requires that the train and its warning devices (horns) be tested per Federal safety guidelines.  If these guidelines are not followed, the G Line will not be put into passenger service.  The City has no jurisdiction over this and Federal law supersedes the City's noise ordinance.
  • The City of Arvada submitted the Notices of Intent to establish Quiet Zones in 2015.  There will be no delay on the City's part in establishing the Zones once we are given permission to proceed from RTD and the Public Utilities Commission.
  • If you would like to speak with someone about train horns, call RTD's customer service line at 303-299-6000 or leave a comment electronically at
  • Information regarding the Federal Railroad Administration (FRA) rules regarding testing of train horns can be found at (search "train horns")

Safety Tips

  • Never trespass on any train track — it is illegal and dangerous.
  • Cross the tracks only at designated crossings, always follow safety signage and obey warning devices like flashing red lights and gate arms.
  • Stay alert and look both ways for a train — you may not hear them coming.
  • Stay off station platforms until they are open to the public.

For after-hour emergencies, please call 303-299-3911. For additional information, please contact RTD at 303-299-6000 or visit
