Using this HO brass model is quite simple. Just take it out of the original box and foam carefully. You can place it on your model train track and enjoy watching it move. Since it has Kadee couplers, it can be easily connected to other train cars. When it comes to handling, be gentle as it's a fragile item, especially being a brass model. As for maintenance, keep it in a dry and clean place to prevent rust or damage. If you notice any issues with the wheel wear, which is currently minimal, you can use a soft cloth to clean the wheels gently. In case you need to use the spare parts, make sure to handle them with care and follow basic model - building techniques. If you have any questions about the product, don't hesitate to contact us.
