They look incredible behind a J (or anything else, for that matter). The cars are in excellent condition, but do take note of the marks on the roof of car 512: there are two close-ups of the roof showing them. The only issue I've observed with the set is that the steam lines, located at the ends of the cars, are not very securely fitted. I believe it is a design flaw, and not unique to my particular set.
