Using your HO scale Alco Models tank car model is simple. Just place it on your model train tracks and enjoy watching it roll along. When handling the model, be careful of the bends in the walkway handrails as they're a bit delicate. To keep your model in good condition, store it in the original box and foam when not in use. This will protect it from dust and accidental damage. If you notice the tarnish getting worse, you can use a soft, dry cloth to gently wipe the surface. Don't use any harsh chemicals or cleaners as they might damage the brass. And remember, since there are no spare parts, handle it with extra care to avoid any further damage. When shipping, we've packed it really well, but still be cautious when unpacking it at your end.
