I saw this route first in Train Simulator and liked it. It was a super great route with nice scenery. I hope you can implement it in the Game if not choose another Austrian route. Thanks for reading this short text and I hope I will see it the next time this route or another Austrian route.
I'd love to see Austria in Gerneral. We already have the Taurus and Soon IC-Coaches. That's a good start
Austria would be absolutely amazing to have in TSW, as it's railways are among the most interesting in Europe. Routes there are very scenic but still busy and fun, just the kind we severely lack in the game at the moment. The rolling stock is also very interesting and diverse. Arlbergbahn is a good choice, but my top pick would be the Tauernbahn as it's my favourite Austrian line.
Ah yes, this was one of my favourite routes to drive in good old Train Simulator. Drove it quite a few times with the ÖBB1044, which was one of my favourite locos in Train Simulator. Would absolutely love to see this route recreated in Train Sim World. EDIT: Good old memories...
