Did a little searching and found this map if people want to have a look-see, but this would be a welcome addition and an interesting set of routes. Franzensfeste - Search (bing.com)
At least a low resolution cab ride is available for this route (which is very important to create it): South Tyrol as kind of austrian related part of Italy also could match for DTG. And this is not the first time where a no information suggestion seemed to have made the race , doesn't matter whether created by ChatGPT or not : https://forums.dovetailgames.com/threads/münchen-salzburg-routes.71211/#post-779931
This is actually a very old video since we dont use the 4 coach flirt anymore we now use the 6 coach one and the stations are very outdated like for example after Brunico should be Brunico Nord but it was built later and at Perca we now have acess to the Kronplatz which is a very popular ski area but otherwise thanks for the help though I think DTG wont be interseted in this or wont be able to get the license or something like that. But if someone from the community wants to give it a try free to use lidar is available: https://geokatalog.buergernetz.bz.it/geokatalog/#!home&layer=p_bz:Elevation:DigitalTerrainModel-2.5m
