About this app

"This app may be used with or without the LEGO® DUPLO® Cargo Train (10875) or LEGO DUPLO Steam Train (10874).


All aboard the DUPLO train! Join the train driver in an exciting adventure on the DUPLO railway. Help the driver by controlling the train’s speed, turning on the headlights, sounding the horn and more!

As part of a brand new experience, your child can collect more than 20 different stickers and place them in the inspirational DUPLO train landscape. In this experience we also have fresh, intuitive controls, including a new color-changing light button.

With the train sets you can place DUPLO action bricks on the rails to make the driver react to your actions. Each action brick can also launch an exciting activity to add even more fun and inspire play with your physical train set.

You can also play without the physical trains and will be able to join the driver on fun activities, collect stickers and have the app react to your actions.

Come with us on a joyful ride and enjoy great fun with LEGO DUPLO Connected Train.

Much fun, based on less functions, ease of use = well done. (only small enhancement recommendation is, to place on/off/reconnect-button on top instead of bottom; this would prevent from always need to take off train from rails)

The train app is simply amazing. It enhances the experience of playing with the train sets and offers a few ideas on how to combine tracks. In general a worthwhile addition. A couple side-notes 1. The train itself is a bit on the heavy side and the tracks have to be laid on non-slippery ground for non-app experience. 2. Lego is one of the best things that can happen to a kid (or grown up for that matter) and it's nice to see how the company evolves with to keep track of time and trends!
