I forgot the train number but the heck from the train DB 182 isn't working only in tsw 2 not on 3 did smb know why?...
The Rapid Transit Dostos have been broken since TSW 3 release, this problem has been reported countless times and still not fixed.
Have you tried pressing either sifa acknowledge or moving the throttle from off to min then off again?
No point - As said it's a known issue, it's broken. Has been since TSW3 came out. The only option is to install another route that has a Dosto Cab Car and use that. Or if you want a real challenge drive in reverse from the Locomotive End (which will enable you to complete the scenario where you are forced to use the cab car provided).
I've tried, many other people have tried. DTG have acknowledged that it's broken. I'm not sure why you think we need to try again? I try it every patch, just in case, but it never gets fixed. It's one of the longest outstanding fixes for TSW3. It works fine in TSW2 though.
