Using this model is easy. Just take it out of the box and place it on your model train track. It's ready to be part of your collection. When handling, be gentle as it's a fragile item. Since it has heavy tarnish and corrosion, you can use a gentle brass cleaner to try and restore its look, but be careful not to damage the painted parts. Store it in a dry place to prevent further corrosion. If you need to clean the metal wheels, use a soft cloth. When shipping it back for a return, make sure to pack it well to avoid any additional damage. And always check with us if you have any questions about its use or maintenance.
