The item has been tested and is in working order. Batteries will be removed before shipping. Requires two AAA batteries. The shipping method may be changed to either Rakuraku Mercari, Yuuyu Mercari, or Eco Mercari. There are no smokers or pets in the household. Control an interactive train. The 33971 Smart Tech Sound Engine is battery-powered and features playful technology and the power to haul heavy loads. Use the red button on top of the engine to record your favorite sound, and play it back when passing through a sound action tunnel. Smart Tech Sound technology allows communication with Smart Tech related items and accessories, enabling more imaginative play with movement, sound, and multi-colored lights and various actions.
