I've been looking at the timetables for this weekend's Arlberg Pass closure, and have seen on OBB's website that the EC164 travels via Salzburg and then non-stop to Bregenz

Does anyone know if this is correct, and what route it takes Salzburg- Bregenz, and if it runs with the SBB panoramacar & OBB restaurant car?
Thanks
