Amtrak venture car project

I want to make a venture car for trainz but I don't know how to model. So I'm going to reskin a European coach, the thing is I can't find any. If you know any good European coaches I can turn into ventures please tell me!

The Venture cars are derived from the European Viaggio cars. You might be able to find a Railjet set (I think there are a couple) which uses the Viaggio cars. It's what I used for mine:

Thank you so much!
