Using this HO scale brass RPO car is easy. Just place it on your model train track and connect it to other cars using the Kadee Couplers. When handling the car, be gentle as it's a fragile item, especially because it's made of brass. To maintain it, keep it in a dry and clean place. Avoid touching the painted surface with dirty hands as it might leave marks. If there's dust on the car, you can use a soft, dry cloth to gently wipe it. Also, store it in the original box and foam when not in use to protect it from damage. When shipping, we've already packed it securely, but once you receive it, make sure to check for any damage during transit. If you're not satisfied, let us know within 30 days and we'll make it right.
