LEGO® DUPLO® Trains

The LEGO® DUPLO® Trains app invites young conductors to explore endless interactive play possibilities with their LEGO® DUPLO® train sets. Designed for toddlers aged 2 and up, this free companion app pairs with special purple Action Bricks in select LEGO® DUPLO® Interactive Train playsets to allow children to remotely control trains, operate lights, customize sounds, and record their own voices. Through video-guided activities, rebuilding ideas, and immersive features, the app supports the development of essential IQ and EQ skills including creative problem-solving, patience, spatial awareness, and motor coordination.

Encouraging healthy digital habits, the app offers offline playability and a safe, age-appropriate experience that fosters learning through fun. When used alongside LEGO® DUPLO® expansion sets and trains like the Train Tunnel and Tracks, Adventure Train, or Cargo Train, it extends physical play into the digital realm, creating a rich and engaging environment for early childhood growth and imagination.
