Using this model is easy. Just place it on the track and connect it to a suitable power source to make it run. When handling, be gentle as it's a fragile brass model. For maintenance, regularly clean the wheels to ensure smooth running. If you notice any loose parts, use the included spare parts to replace them. Keep it in a dry and dust-free place when not in use. Remember, when shipping internationally, you're responsible for imports, duties, and tariffs.
