Using your HO scale brass tank car is easy. You can simply place it on your model train track and connect it to other cars using the Kadee couplers. When handling the tank car, be careful as some of the stirrup steps are already bent, and further handling might cause more damage. For storage, keep it in its original box to protect it from dust and scratches. If you notice any dirt or grime on the car, you can use a soft, dry cloth to gently wipe it clean. Avoid using any harsh chemicals or abrasive materials as they can damage the paint and decals. And remember, if you're not satisfied with your purchase, you can return it within 30 days for a full refund, just pay the return shipping (unless it arrives damaged).
