10425 Train Tunnel and Tracks Expansion Set

Extend toddlers’ train adventures with the Train Tunnel and Tracks Expansion Set (10425) toy for toddlers. 
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. 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).
