Yesterday I bought the add-on Mannheim-Karlsruhe. There is the BR 425 included. But when I start playing I heard that there must be something with the sound from this train. I know hat it sound but this is not the right one. Can sb help me with this sound problem?
That is just down to DTG - suggest you look for a patch Maybe on RailSim.de? https://rail-sim.de/forum/filebase/filebase/1224-train-simulator/
