This evening I did uncoupled the cars but as soon as the train is ready to go and the couplers coupled together again. I am not sure how to stay uncople the cars after click at the bottom of the F5 HUD then the train is ready to move. I have tried this three or four times and give up with this.I am not sure how to do the right way to uncouple the cars then the train is ready to move.
