Toddlers take the wheel with the Interactive Adventure Train set (10427). With this toy train, kids aged 2 and up can choose the destination and set off on a journey full of light, sound and educational play. This building toy includes a selection of bricks to create a park, beach, train station or family home, encouraging toddlers' curiosity. It's an educational toy that stretches toddlers' patience, fine motor skills and creativity as they focus on building the train track and plotting the route. The 3 action bricks bring the play to life and make the toy train make realistic sounds as it passes over it. Toddlers can use the special customization brick to play their own sounds recorded with the free LEGO® DUPLO® Interactive Trains app, which can also be used to control the train with a handheld electronic device.
