Choo choo twitter is adorable! It's like watching our pug get angry. Anywho, yeah you can probably do a train from Barcelona to Moscow, but . . . I'm guessing you almost never would, which is the point. It's why national HSR is silly.

You'd think that it would be significantly easier to build a train between the US coasts than through several sovereign nations, but what do I know, I'm just a choo choo.
