Using this HO scale brass diner is simple. Just place it on your model train track. When handling, be gentle as it's a fragile item. To keep it in great condition, store it in the original box and foam when not in use. Avoid exposing it to moisture as it may cause tarnish. If you notice any tarnish, you can use a soft, dry cloth to gently clean it. Don't try to add couplers on your own unless you have experience, as it might damage the model. And remember, if you're not satisfied with your purchase, you can return it within 30 days.
