I conclude, that either SVV forgot to upload the newer version or the map is made by ÖBB in the first place and the new version was not given out to SVV (yet).
Anyway, I updated all existing lines in the dataset according to the newer version and added S3 and S$ from the BRB as well as line R3.
You can find a network map on the website of the SVV, but it has not been updated since November 2022.
