Aren’t both A’s set to the same default from the factory? If so, could you run them as an engine because the trailing unit defaults to run backwards out of the box?
That's been my experience with Legacy A-A sets. If you change the engine ID of both to the same number, they still run that way. So they don't need to be lashed up (Ooops, said the dirty word) as you'd do under Legacy with unpaired powered engines. I always wondered how Lionel managed this but never inquired.
