Using this HO scale brass train model is quite straightforward. Just connect it to your analog - DC power source, and it will start running. Make sure to use a compatible power supply for smooth operation. When it comes to handling, be gentle as the model is fragile, especially the brass parts. Since the box and foam show some wear, take extra care when taking the model out and putting it back. For maintenance, periodically lubricate the gearbox as it was recently serviced in this way. Check the wheels regularly for any signs of increased wear. If you notice more plating coming off or any other issues, it might need some attention. Store the model in a dry place to prevent any further water - related damage. If you're shipping it back for a return, follow the shipping instructions provided to avoid any damage during transit.
