Here's an excerpt from the Real Time blog:
Florida East Coast Railway will test a different horn configuration for its new locomotives hoping to quiet blasts that have drawn hundreds of complaints from the Treasure Coast to Fort Lauderdale.
FECR spokeswoman Debra Phillips said horn manufacturer Nathan Airchime is looking to replace one of the chimes on the new engine’s five-chime horns. Florida East Coast Railway will then test to determine if the change makes a difference.
“There is no set date for the test and no set cost,” [emphasis added] Phillips said.
Still, the idea that FECR is at least working on a possible solution may be some consolation to residents who live and work along the tracks.
