Using this HO scale diner model is easy. Just take it out of the original box and foam carefully. Since it doesn't have couplers installed, you can add them if you want to connect it to other train cars. There's no lighting in it, so if you plan to add lights later, you'll need to do some modifications. When handling the model, be gentle as it's made of brass and can be fragile. Keep it away from sharp objects to avoid scratches. For maintenance, you can use a soft, dry cloth to wipe off any dust. If it gets dirty, you can use a mild cleaner on a cloth, but make sure to dry it thoroughly. Store it in a cool, dry place to prevent tarnishing. If you need to return it, just contact us within 30 days. Remember, you'll be responsible for return shipping unless the item arrived damaged.
