We recommend using alkaline batteries with our products, as they are great for long-term use and help optimize performance. We don't recommend using Carbon-Zinc batteries. While Carbon-Zinc batteries may work well with low-power devices, they can drain after a short period of time and cause certain products to not function properly.

Fisher-Price takes great pride in the Wooden Railway line of products and accessories that we produce and quality is very important to us. We thought it would be helpful to let you know that we include a small amount of plastic on some of our wooden products to further ensure their improved strength.
