Choo-choo! Hop aboard the LEGO® DUPLO® Trains app with your little conductor and discover new ways to play! Allow your child the thrill of remote controlling the train, operating lights, recording their voice and customizing sounds with presets when used with the special purple Action Brick in the playsets.
Get inspired with trainloads of rebuilding ideas, video guidance and extended-functionality features for LEGO DUPLO Interactive Trains playsets. This optional companion app can support your child’s development of essential skills such as creative problem-solving and learning patience.
When kids play, they learn and grow. Our activities are designed to fit your child’s development stage and help them develop a balance of the IQ (cognitive, creative and physical) and EQ (social and emotional) skills they need for the best start in life. LEGO DUPLO Interactive Trains and the app not only support creative solutions and learning patience, but they also help toddlers learn to predict, improve hand-eye coordination and develop spatial awareness. Additionally, they promote emotional control, focus and fine and gross motor skills.
