Hi, I can be wrong but it was planend to support the BR425 on the Aachen Köln route on the timetable right? But they still not there at the moment.. Can you explain about this issue? I have all the old addons included the Bochum Duisburg route offcourse!
Unfortunately it isn't the case and wasn't announced. Ruhr-Sieg Nord will add RE 1 services for the Dosto and Rhein-Ruhr Osten will add S-Bahn services for the 422.
They said that the 425 will not be added to the route until the RRO DLC comes out. From some reason it's linked to that DLC even though the 425 is not in it. Never mind, it's the 422 I was thinking of.
