This is a nice working train set. The smoking feature is untested and not sure if the uncoupling piece of track works to uncouple cars. I don't think it does. Other than that it seems to work okay. All of the cars and the Engine look to be in fantastic condition. The transformer works as it should but looks a little rough and there is a piece of tape on the cord. The tracks have rust on them and the original box has a few issues. What you see in the pictures is exactly what you will receive.
