When using the DB BR 143 (from DRA) on MSB, the Dostos coaches aren't behaving as they should. When I try to turn the coach lights on from inside the 143 cab it has no effect and the tail lights on the cab car aren't on and when trying to switch them on they don't turn on. Then when I try to drive from the cab car the headlights are working either and the coach lights still don't turn on.
