Using this self - propelled Sperry Rail Service car model is straightforward. Just connect it to an analog DC power source and watch it run. When handling, be gentle as it's a fragile brass model. For storage, keep it in the original box and foam to prevent damage. If you notice any excessive noise or performance issues, check the motor and gearbox. Clean the model regularly with a soft, dry cloth to maintain its factory paintwork. When shipping it back (if needed), make sure to pack it securely to avoid any new damages. And remember, if you're not satisfied, you have a 30 - day no - questions - asked money - back policy, though you'll be responsible for return shipping unless the item arrived damaged.
