Using this HO scale brass model is easy. Just place it on your model train track and enjoy watching it roll. When handling the model, be gentle as it's fragile, especially the brass parts. To keep it in good condition, store it in the original box and foam when not in use. Avoid exposing it to moisture and extreme temperatures as this can cause tarnishing. If you notice any minor tarnish, you can use a soft, dry cloth to gently wipe the surface. Remember, there are no spare parts, so handle it with extra care to avoid any damage. And don't forget to check the shipping and payment details when you make your purchase.
