Yes, I have. Many times. It's wonderful!
I travel by train in Europe every chance I get. It's wonderful. And it's a mirage. Whenever I do so, it's with the knowledge that well over half of the price of my ticket is subsidized mostly be working class citizens with half the standard of living that I have who rarely partake of the pleasure. I appreciate their sacrifice on my behalf.
But what does any of that have to do with my post other than being a feeble attempt at changing the subject? High speed trains in France & Spain have done nothing to stave off their inevitable bankruptcy. Doing the same here certainly won't work any better for us. And that is some reality for you.
