Scenic train from Vienna to Zurich

There is a train from Vienna to Zürich every 2 hours, they all follow the same route (Vienna - Salzburg - Innsbruck - Feldkirch - Zürich).
The trains leave Vienna 30 minutes past odd hours (05:30, 07:30, 09:30, 11:30 etc) and it takes 7h50 - a long journey.
After Salzburg you are going through the Alps lengthways. you see lots of mountains. There are no special panoramic coaches, it is just a normal intercity train.

Yesterday, I flew from Vienna to Zurich in 1.5 hours. Mountains are just as pretty from the air. That’s such a long train ride...

I researched this route last year using the same weblinks. Ultimately, I needed to fly out of Munich, but this is on my list for the future!

And once past St. Anton I would suggest that the view is not necessarily scenic. At least not as much from Salzburg through to St. Anton. Much could also be said on how scenic the ride is from Vienna to Salzburg. But this is all up to the individual.
