The country's first private high-speed rail service is opening this month in Florida, promising to transform congested South Florida highways by taking as many as 3 million cars off the road. The ambitious $3 billion Brightline express project will run along the state's densest population corridor with more than 6 million residents and a regular influx of tourists. The project, funded by All Aboard Florida, represents the first test into the long-awaited U.S. move into high-speed rail, says John Renne, director of the Center for Urban and Environmental Solutions at Florida Atlantic University. All Aboard Florida secured state approval in October to sell bonds to fund the project. The company has said no public money will be used. Renne says the trip from West Palm to Miami, which can take up to five hours round trip in a car, will take about 60 minutes each way on the train. Brightline trains will have their own dedicated set of tracks, built alongside 19th century lines that still carry cargo trains. The return to passenger trains will revive a line that stopped running on those old tracks in the 1960s, with the arrival of the federal highway program. "The federal highway system expanded ... and everyone got off trains and into cars," John Guitar of All Aboard Florida [said]. "And we've done a full circle now that the traffic and congestion and gas prices are so bad, people are looking for alternatives to get out of their cars and find other ways to get around the state."
