Using this model train car is easy. Just connect it to your model train set using the Kadee Couplers. When handling it, be careful as it's a fragile item, especially since it's made of brass. If you're storing it, keep it in the original box and foam to prevent any damage. In terms of maintenance, gently dust it off regularly to keep the paint and decals looking good. Since both steam line connections are missing and one stirrup step is slightly bent, don't try to force any repairs on your own as it might cause more damage. If you have any concerns, you can contact us for advice. Also, remember that if you're shipping it back under the return policy, pack it securely to avoid further damage.
