Train horns can stay quiet at more highway crossings

The US Transportation Department has changed the definition of a "non-traversable curb" for train horn rules. This means more highway crossings can now be designated as "quiet zones" where trains do not have to sound their horns.

For years, some highway crossings with specific curb designs still required trains to blast their horns, even if they were otherwise safe. This rule change aligns the official definition with existing waivers, making it easier for communities to establish quiet zones. It reduces noise pollution for residents living near these crossings.
