With the FIS of the DB BR 422 on the Rhine Ruhr East it is no longer possible to set the correct line. I wanted to make a trip as the S8 in the direction of Wuppertal and this line does not exist in the FIS.
The actually service goes all the way to Mönchengladbach, but in the game, the route is only made as far as Wuppertal-Steinbeck. So put the FIS on S8 Mönchengladbach.
Then, you have the HRR BR422 now. The game can't sometimes see the difference between the RRO and HRR BR422.
