First time I've heard of this.
I know there was a plan to build a high speed train from Victorville to Las Vegas but it has not even come close to getting off the ground.
The only bullet train plan that is somewhat happening is the one that will eventually connect LA to San Francisco and LA to San Deigo. And even this project is running into layers upon layers of bureaucratic red tape. I'm in my 20's, I'll be surprised if its built by the time I'm in my 50's.
