I hated to see old Willie Green go. He was fun to play with, like a slice of DU without having to wade through all the other crap.
I know. I went round with him a few times "back in the day".
In these days of virtuality, there seems to be less need for speedy trips. Economical travel seems to have (obviously) value still.
I'd guess that air travel (relatively low infrastructure investments) is more economical than HS rail. Of course the TSA has screwed up efficient business air travel over the days of OJ running down the concourse.
