LEGO Duplo - Big Interactive Community Train (10428)Preschoolers use creative thinking to plot a route for the Push&Go toy passenger train and complete fun problem solving tasks as they go. They can load the train with cargo, charge the engine or wash the cars. Each activity comes to life with lights and sounds as the toy train passes over one of the 5 action bricks. This set also helps develop patience and curiosity as young children experiment with new ways to build their train tracks. Dimensions:
