Each piece of the train is beautifully cloisonne decorated and the wheels on each piece work well. On the engine piece, when the wheels are moving, the side bars connected to the wheels move along with the engine. The engine measures approximately 6″ long, the middle and third car both measures approximately 4″ long. This is a nice heavy metal set and would add a lot of color to your Holiday decorations. If there is a problem with the item when you receive it, please let me know before giving me feedback and I will be happy to work with you on a solution.
