Loco Add On: "x-Wagen" + "Br 143" for "Rein Ruhr Osten" and "Hauptstrecke Rein Ruhr" Whats about the iconic x-Wagen of the S-Bahn Rein Ruhr. Which you could drive on "Rein Ruhr Osten" and "Hauptstrecke Rein Ruhr".
Orange and white version DB BR111 X Wagen because a 1980s RRO HRR would have featured them due to DB BR143 being Deutsche Reichsbahn DDR locomotive DR BR243
