Although the DB BR442 'Talent 2' has already appeared in Train Sim World 2, we only have three variants of that unit in the game (credit where it's due, I admire DTG's efforts to make each variant distinctly different from the others). There's so much potential with these trains, in terms of the amount of variants there are and what routes could be made for them to run on (such as Koblenz to Trier, with 2 and 4-car units included). But I want to focus on just one variant for this suggestion; the National Express BR9442. These are either three or five-car units, and they run on the Rhein-Ruhr Express network (as well as Rhein-Münsterland). They could be made as an add-on for the existing Rhein-Ruhr Osten route, as they run through Wuppertal and Hagen in real life on the RE4 service (Aachen to Dortmund). They'd make the route more interesting with their distinctive livery, and they could also be used as Ai traffic at Koln Hauptbahnhof on the Schnellfahrstrecke route. So to summarise, I'd like to see this specific variant of the Talent 2 in Train Sim World 2; the BR9442 in both the 3 and 5-car variants. They would be an add-on for Rhein-Ruhr Osten, adding at least three scenarios and (insert number here) extra services to timetable mode. As it stands now, RRO doesn't look too realistic with just the DB BR422 and MRCE BR185.5 (not counting the rolling stock from Main-Spessart Bahn).

The base model for this is your DB BR442 from Schnellfahrstrecke Köln-Aachen Riesa-Dresden and Rapid Transit. Those just need a reskin and a matching automatic announcement system being Anna instead of Ingo Ruff which the Silver and Red DB BR442s have.
