About LEGO Interactive Adventure Train
Four figures can board this 57-piece interactive train that responds with lights and sounds as it travels around the track. The set includes 14 track pieces that form a complete loop measuring 71 cm wide by 57 cm deep when assembled, along with three destination builds representing a station, park and beach.
The train features three interactive action bricks that trigger different audio and visual effects during play. These require four AAA batteries (sold separately) to power the lights and sound system. Toddlers can choose items to pack aboard the train, then plan routes between the different destinations, developing problem-solving skills through creative play.
Interactive Features
A companion app allows children to record custom sounds for their train and control it remotely using a tablet or smartphone. The digital integration extends the play experience beyond the physical building elements, giving toddlers additional ways to customise their railway adventures.
The set is designed for children aged 2 and above, with all pieces sized appropriately for small hands. The larger DUPLO brick format ensures safe play while still offering the building complexity that develops fine motor skills and spatial reasoning.
