As a German, I find it so funny the way it's painted TRC colors outside, yet the inside still looks exactly like all other German DB Regio trains. These double decker push-pull-trains are some of my favorite trains. They fit a looot of people and the seats are comfortable. Because the locomotive is separate instead of being a DMU/EMU, you don't hear the engine typically. So on a good railway, you don't even feel or hear how you are moving. I believe they are the ones listed in this Wikipedia article as 3rd generation: en.m.wikipedia.org/wiki/Bombardier_Double-deck_Coach the display even looks the same and also indicated the line number RE9, just as seen in the video.
