Thanks , that part i know .
Its a mountain line in the Andes with tight curves.
I run passengers trains over it myself , but i know , in a scenario , the AI wil not do that .
Changing the properties is something i do later .
edit : i have a switchback in that route on a steap mountain . Can the AI do a switchback ?
