I got a Thoroughbred train set this weekend and I found the caboose bogies can spin 360 degrees which makes it the most difficult car to get on rail as they can literally sideways if you are not holding both in place with your fingers. None of the other cars in the set or the other rolling stock I bought from either Bachmann, or another brand has bogies that spin they are usually stopped by the coupler housing. So is that normal for the caboose bogies to spin like that?
