ORLANDO, Fla. (AP) — Central Florida residents may in the coming year begin to appreciate notes of nostalgia when trains chug through the region, trumpeting over and over their melody of two long blasts, a short and a long.

That's because Orange and Seminole counties, their cities and Kissimmee are on track to finish what they started many years ago, establishing "quiet zones" at dozens of safety-enhanced crossings where engineers will no longer blow their horns unless danger arises.

The Orlando Sentinel report s while many crossings will get upgrades this year, uncertainty remains about the timing of final federal approval required to go live with quiet zones.

Orlando, however doesn't anticipate going entirely quiet-zone for about two years.
