LEGO® DUPLO® Connected Train

Control a connected train toy with an app designed for toddlers—LEGO® DUPLO® Connected Train brings the magic of physical play into the digital world. This app works perfectly with the LEGO DUPLO Cargo Train or Steam Train sets, but also stands alone as a fun, screen-based experience for young learners.

Your child becomes the train driver, taking control of speed, headlights, horn, and more as they guide their train through an exciting railway adventure. The intuitive interface is built for little hands and developing minds, with fresh, toddler-friendly visuals and interactions that encourage exploration without overwhelming buttons or menus. A color-changing light button adds a magical touch that keeps young players engaged.

Collect over 20 different stickers to decorate an inspirational DUPLO train landscape, turning the app into a creative canvas where your child's imagination leads the way. Each sticker placed is a small achievement that builds confidence and encourages repeated play.

If you own a physical LEGO DUPLO train set, action bricks placed on the rails trigger real reactions in the app—creating a seamless bridge between the tangible toy and digital experience. These action bricks also launch age-appropriate activities that deepen engagement with both the app and the physical train set. The connection happens automatically: simply open the app, select your train, turn on the physical set, and they sync instantly.

Even without the physical train, children enjoy the full adventure, complete activities, and collect stickers while the app responds to their taps and choices. Every interaction feels rewarding, building early digital literacy in a safe, controlled environment.

Parents will appreciate the thoughtful design: no in-app purchases, no third-party ads, and no data tracking. A parental gate protects access to further app information and LEGO DUPLO details. LEGO DUPLO Connected Train reflects decades of expertise in child development, crafted with educators and parents to ensure safety, creativity, and lasting fun.

Boarding the LEGO® DUPLO® Connected Train opens a world where physical toys and digital play work together, sparking joy and imaginative adventures for toddlers and preschoolers.
