Using your HO scale brass EMD F9A locomotive is quite simple. Just connect it to an analog DC power source, and it will start running smoothly on your tracks. Remember, since it has no lighting, you won't have that feature, but it still looks great with its interior cab detail. When handling the locomotive, be gentle as it's a fragile item. Avoid dropping it or subjecting it to rough impacts. For maintenance, keep it in a dry place to prevent tarnishing. You can use a soft cloth to gently clean the body from time to time. Check the wheel wear occasionally; currently, it has minimal wear, but regular inspection will help you notice any changes. If you plan to install couplers, use the existing mounting screws. When shipping, we've packed it carefully, but if you need to reship it, follow similar high - quality packing standards. Enjoy your new locomotive!
