Using your HO scale brass model train is easy. First, make sure you're using an analog DC power source as it's designed for this type of control. Just connect it to the tracks and power it on. It should start running smoothly right away. When it comes to maintenance, keep an eye on the wheels. Although the wheel wear is minimal, you can clean them gently from time to time to keep the model running well. The motor may produce moderate noise, which is normal for this model. If you want to add numbering to the model, you can use the included decals. Just be careful when applying them to get a neat look. When it's time to store the model, keep it in the original box and foam to protect it from damage. And remember, if you're not satisfied with your purchase, you can return it within 30 days for a full refund, but you'll be responsible for the return shipping cost unless the item arrives damaged.
