and would it be economical? If you mean "Can pay its own costs", only if the effing feds don't touch it. Then, maybe.
I checked on taking a train home instead of flying from El Paso. There is indeed a train that runs. Every few days. It costs as much as a plane ticket, and takes 36 hours to make the trip. And Amtrak is subsidized by how much of our money annually?
Screw you, Biden, I don't care if you adore it. Cut Amtrak loose and tell it "Make your costs, or sink." It'll either streamline things or go under. And if it goes under, I don't doubt someone will buy at least parts of it and open a line, as there is a market for the service.
