LEGO DUPLO train track extension toddler toy
Extend toddlers’ train adventures with the Train Tunnel and Tracks Expansion Set (10425) toy for toddlers. Preschool kids aged 2+ grow their learning adventures as they add a tunnel and extra track to their LEGO DUPLO Town interactive toy train sets (10427 and 10428, sold separately).
This creative building toy comes with a tunnel build and a 10-piece track, including a funnel element and a 2-way points switch so toddlers can change their train’s direction of travel. The action brick lights up the dark tunnel when activated by the interactive train from sets 10427 and 10428.
This kids’ learning toy encourages a toddler’s development. By extending the train track through the toy tunnel, preschoolers learn spatial awareness. Using problem-solving skills to combine the toy track and prediction skills to determine the train’s destination, toddlers develop patience and focus as they discover the many routes they can make.

The LEGO 10425 Train Tunnel and Tracks Expansion Set was released in the year 2025. The set contains 20 parts. The set comes with no minifigures and 1 instruction. The set is suitable for children from 2 year old.
