Yes they were the same cars but I put the stock MTL couplers on for the show (except for the trailing car since nothing would be connected to the end). I tested with the short shank and they didn't test well with my curves at home. Just now I tried it with the long shank version and it's much better but still needs broader curves than I have. I can't remember what the radius is for my kids' unitrak setup (not easily pulled up). I'll try to post a photo of the long shanks on these cars in the next few days.
