Toddlers aged 3 and up can embark on an imaginative journey with the Big Interactive Neighborhood Train (10428). This fun, feature-packed set includes 4 different figures and provides hours of playful learning. Toddlers' learning journey starts at the train station. They use creative thinking to plan a route for the Push & Go passenger train, completing fun tasks along the way. They can fill the train with cargo, charge the engine or wash the carriages. Each activity comes to life with lights and sounds as the toy train passes over 1 of the 5 action bricks. This set also helps develop patience and curiosity as toddlers experiment with new ways to build their train track. With the free LEGO® DUPLO® Interactive Trains app, toddlers can record their own sounds for the train journey and control the engine using a wearable electronic device. The app also gives families inspiration for alternative models.
