Little ones can embark on a railway adventure with the LEGO DUPLO Big Interactive Community Train (10428) building set for boys and girls ages 3 and up. This train set for toddlers is packed with fun features and functions, including 4 diverse figures, 5 action bricks and detailed accessories for hours of interactive play. Children can load the train with cargo, charge the engine, or wash the carriages. Each activity is brought to life with lights and sounds as the toy train passes over one of the action bricks. Toddlers will also set out on a learning journey, starting at the toy train station. Preschoolers are encouraged to use creative thinking to plot a route for the Push&Go passenger train toy, using problem-solving skills on tasks as they move ahead. The free LEGO DUPLO Interactive Trains app lets little ones record and create their own sound effects and drive the locomotive using a portable electronic device. Contains 103 pieces.
