A couple months ago we were discussing the introduction of RailJet service between Prague and Vienna (and on to Graz). The Austrian RailJet has already been advertised at the train stations in Vienna. We were also speculating on the savings in time, because of the condition of some tracks in the Czech Republic.
There was an article about the Czech Railways "RailJet". Yes, they adopted the name "RailJet" for their new high-speed trains. They are a nice blue and white.
The article said that the Prague - Brno service is starting soon, and the service to Vienna and Graz will start at the end of the year.
The most important thing is that they said the new service (also using Austrian "RailJet" equipment) will cut 30 minutes off the travel time between Prague and Vienna.
So, that answered all of our questions. Thank you, České dráhy!
