Using your HO Brass Oriental Limited EMD GP9 locomotive is a breeze. Just connect it to your analog - DC power source, and it'll start running smoothly on the tracks. When handling the locomotive, be gentle as it's a fragile item, especially since it's a brass model. For maintenance, check the wheels regularly for any signs of wear, though this model has very little wheel wear to begin with. Clean the locomotive with a soft, dry cloth to keep it looking good. If you notice any unusual noise, it might be a good idea to give the motor and gearbox a quick check. Keep it stored in the original box and foam when not in use to protect it from damage. Remember, if you're not satisfied with your purchase, you can get a refund within 30 days, just let us know!
