I ended up in a Hungarian Train (it said MÁV-START on the outside) that somehow went the way I needed. I was shocked. It felt so much friendlier than ÖBB's Railjet (which I usually take). They even have USB-Charging-Ports. This really blew my mind. Even the tables felt better than the ones in a RailJet. Sadly I didn't manage to take any more pictures.
