Trains anyone has found that can't be uncoupled once coupled to something: 1938 Stock (uncouple button doesn't work) Class 483? (haven't tried it myself) BR403 (uncouple button doesn't work) BR406 (uncouple button doesn't work) BR642? (haven't tried it myself) Class 43 (doesn't have a coupler lock prompt at the back)
Just to be clear on this issue - there are no plans to go back and add coupler interactives to stock that doesn't currently have it.
and for the ICE 3 i think you say that was maybe possible and still possible in timetable ? only AI train
