I have an AI train via a portal. It had a caboose attached. The caboose is dropped on a siding(far right) and the engine continues to pickup/couple to some passenger cars-consist 1. All ok. Now I want this train to return to the siding where the caboose is and couple it to the back of the train. The problem is that it will only couple to the front of the train(engine). I reversed the siding track direction by relaying the track. I turned the caboose around. I can't think of any other steps to force the caboose to be coupled to the back of the train.
Yes, a caboose is not appropriate in this case but just trying things.
