It’s all a huge scam. There was a viable rail system called Mag Lev, but then Harry Reid got into it with his shill Sig Rogich and Desert Xpress. Rogich immediately eaded Republicans For Reid.
A rail line is time-tested technology and a lot cheaper to build and operate. Considering that this is to be a total private sector operation, if it turns out to be a scam, then Fortress Capital will lose its shirt.
