About this app

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 controlling the train remotely, operating lights, recording their voice and customising 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 patience.
When kids play, they learn and grow. Our activities are designed to match your child’s developmental stage and help them to 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 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.

At least 10427 set is poor, the action brick function is confusing, without app pretty much only thing is to drive around and listen to sounds, and wonder why the train sometimes stops and sometimes does not stop on action bricks. Seems that app only contains videos about playing with the set. Only functions seem to be to drive the train and change the sound on the star brick. app shows the previous train set model as "expired". Train stopped making sounds after a day, FW update via app helped.

This app is terrible compared to the old one. The old one made playing with the trains fun if you didn't have them with you at the moment. This app is just an advertisement for the sets and only allows you to control the basic functionality of the train when you have them.
