To address the issue with all of the timetable's BR442 RE9 services starting from Aachen being unplayable because of wrong formations without pantographs, I've contacted the author annadess who did the fix for TSW2, made the mod TSW4 compatible and uploaded it on trainsimcommunity. Should be approved and live soon.
DTG are aware but, looking at how long this bug is present, they are working a thousand times slower than the modders. I mean, the logout function of the forums is broken for a year or so, they said they are working on it. But whoever it is that is "working" on it should be fired!
