Using this HO scale brass model is easy. Just place it on your model train track and enjoy watching it move. Since it has no couplers, you can choose to add your own if you want to connect it to other cars. When handling the model, be gentle as the brass is delicate. The underbody is nicely detailed, so try not to touch it too much to avoid scratching. If the model gets dirty, you can use a soft, dry cloth to gently wipe it. Store it in the original box and foam when not in use to protect it from dust and damage. Keep in mind that one etched grill cover on the underbody is slightly bent and one rear stirrup on the right side is missing, so be careful not to cause further damage to these parts.
