Me too! But why did you need a quick connection between Klagenfurt and Graz as a child? I would have rather longed for a high speed train between Hermagor and Villach ;-)
I would have never expected to read about Hermagor in an HN thread. Greetings from the Werbutz Alm!
At least I got to enjoy the highway connection between Noetsch and Villach when I was a child. Both of those things were big things due to local politics (hi Haider) when I grew up. Practically I did not care. But it was ubiquitous for a while in the news.
What kid doesn't go through a 'train phase?' and a grand plan to improve the railway could be exciting to a child even if it's more spectacle than utility.
