Train Trip in Austria: Railjet Express from Vienna to Innsbruck

Railjet is a brand of high-speed train served by Austrian Railway Company, ÖBB.
Railjet has a broad network not only domestically, but also internationally like Hungary, Switzerland, Germany, Italy, Czech Republic, etc.
Its frequency is high and really convenient to trip around the central Europe.
This time, I rode Railjet Express (a faster type of Railjet) from Vienna Central Station (Hauptbahnhof in German) to Innsbruck.
While it's a four hour trip, really cozy and confortable trip with the view of fantastic Alpine's landscape.
2nd-class one way ticket costs 79.9 EUR booked in one-month advance.
More reasonable ticket would be available at different departing time.
