Let us hope that it doesn't! There isn't a passenger carrying train anywhere in this country that survives by it's own merit. Every one of them receive gubmint subsidies, usually for a sizable, if not majority, portion of their operating budget.
Local powers that be in my area have been "studying" a high speed maglev train that would run between Atlanta and Chattanooga, and eventually on to Nashville. I haven't kept track of what they've spent thus far with this "study", but it's in the tens of millions of dollars last time I checked. In reality, what it would provide is a corridor for a pipeline for Atlanta to tap water from the Tennessee River now that they've planned so poorly on fresh water reservoirs after inviting 5 million people to move there.....
One of the problems is that the mass transit systems keep trying to operate as social experiments. In the buses, they run through the worst parts of town, and serve as transport systems for gang bangers. In San Antonio, one of the malls withdrew permission for the city to use the mall as a pick up and drop off point because all they brought in were shoplifters and muggers.
I suggested, many years ago, that the city of Austin, instead of running hundreds of buses that only have three or four people in them (ever wonder why most city buses now have the designs that cover the windows so you can’t see inside?) that they look at a mass transit loop. They’d set up a trolley or monorail that would start at the international airport and make a big loop through the city. Hotels could pay a fee to make their locations a drop off point, which would be covered and have baggage assistance. Then it would loop through the convention center, the UT football, baseball and basketball stadiums, the state capital, and the major malls. The plans that were approved, but never implemented, went straight through all of the projects, and, of course, included free fare. The buses run the approved routes, but few paying people use them, so they lose money.
They could use Vokswagen Beetles and save a lot of money and still haul the same number of passengers.
