BOCA RATON, Fla. -

All Aboard Florida has announced a continuous quiet zone stretching from Hallandale Beach to downtown West Palm Beach.

The announcement was made Wednesday during separate news conferences in Boca Raton and Hollywood.

All Aboard Florida is a privately funded, 235-mile express passenger rail service that will transport passengers to and from central Florida and Miami, with stops in Fort Lauderdale and West Palm Beach.

Quiet zones are areas that, because of safety features, the Federal Railroad Administration will allow trains to pass through without sounding their horns.

President Michael Reininger said safety has always been All Aboard Florida's top priority and now trains using the easternmost Florida East Coast Railway track will also be the quietest.

He said All Aboard Florida is investing $60 million in safety improvements between Miami-Dade and Palm Beach counties.
