Honestly, as a European going to the us, it was shocking how bad the train system is. But I get it, places in the us are too far spread apart, so that it is more difficult to connect them.
If there are airport like security checks, even less people will use it. Good for the freight trains though, since they'll have the tracks to themselves.
I can't really comment on the article, since it bans EU visitors, but judging by comments here, I'm afraid the system will only get worse.
