Using this locomotive is easy. Just place it on your train track and let it roll along. Since it's an unpowered unit, you'll need to have a powered unit in your train setup to make it move. When handling the locomotive, be gentle as it's a fragile item. To maintain it, keep it in a dry place away from direct sunlight. You can use a soft, dry cloth to gently wipe off any dust. If you want to clean it further, use a mild cleaning solution and a soft brush, but be very careful not to damage the paint or the details. Remember, it's a custom - painted model, so take extra care. When shipping it back (if you decide to return it), make sure to use proper packaging to avoid any further damage.
