Using this model train set is simple. Just place it on your model train track and let it roll. However, since it doesn't come with trucks, you'll need to have your own or find compatible ones if you want to enhance its functionality. When handling the set, be gentle because these are fragile items, especially the brass parts. As for maintenance, keep it in a dry and clean place to prevent further tarnishing. If you notice any loose parts, you can use the spare parts that come with the set to fix them. But remember, the solder work on these early Korean-built models isn't perfect, so don't be too hard on it.
