I think there's appetite for it to happen. There's a new rail line going in between the LA area and Las Vegas. Amtrak is now running a new route between Minneapolis and Chicago. I'm sure there are more like this.

Certainly there are challenges with rail in some of the more sparsely populated areas, where it doesn't necessarily make sense. I think it will start by building out regional networks. It certainly won't happen by optimizing for NYC to LA.
