Could be a real sreenshot from the new route: München-Augsburg, because in the background we see a DB BR423 S-Bahn. We already have a BR425. Of course they look very similar, but the door configuration is a different one and in the screenshot it looks like the upcoming BR423. The graphic also looks like TSW not like TS...
It has the white markings above the door, the 425 does not have that. Also I don't know if the TS version had these but from what I heard this is a relatively new change made to the train, thus it would further the idea that this is from the new TSW route and not from TS.
