Graz/Klagenfurt – It took a long time, but with the 33 kilometer long Koralm tunnel and the associated high-speed lines, the south of Austria also became interesting for the private rail transport provider Westbahn. On Sunday, March 1st, the Westbahn will start with three daily trains there and back from Vienna Central Station via Graz and Klagenfurt to Villach. Three single-decker sets are used on the southern line, in contrast to the double-decker wagons on the western line.
