LEGO Duplo 10427 Interactive Adventure Train

LEGO DUPLO set 10427, Interactive Adventure Train, represents an interactive adventure train in the Trains subtheme. Released in 2025, it contains 57 pieces and belongs to the DUPLO range, where simple construction and direct handling define the building experience.

Interactive Adventure Train sits under the DUPLO root theme and specifically within Trains. Its subject is a play train with track and interactive elements, rather than a detailed railway replica. It follows the DUPLO train approach, where accessibility, movement and hands-on play are more important than fine decorative accuracy.

The set contains 57 pieces.

This set is mainly suited to play and to an early, simple railway setting in DUPLO form. It can sit alongside other DUPLO Trains sets through its track parts and functional components. Within the theme, its identity comes from the interactive play features and from a compact parts count rather than from display complexity.
