Using this O scale Deep Rock 3 - Dome Tank Car is easy. Just place it on your model train track. When handling, be gentle as it's a fragile brass model. Keep it away from sharp objects to avoid scratches. For maintenance, use a soft, dry cloth to clean the surface every once in a while. If you notice any loose parts, like the Kadee couplers, handle them carefully and consider getting help from a model train expert.
