This HO scale brass test car is a great addition to your collection. To use it, simply place it on your model train tracks just like you would with any other car in your set. When handling the car, be gentle as the handrails are bent and might be a bit fragile. To maintain it, keep it in a dry and dust - free place. You can use a soft, dry cloth to gently wipe the car if it gets dirty. Avoid using any harsh chemicals or abrasive materials on the paint, as the custom orange paint has some wear and could get damaged further. Also, make sure to store it in the original box and foam insert when not in use to protect it from accidental bumps and scratches. If you have any issues with the product, reach out to us within 30 days for a hassle - free return.
