LEGO Duplo 10425 Train Tunnel and Track Expansion Set LEGO building set Multicolor

Expand toddlers' train adventures with the Train Tunnel and Track Expansion Set (10425). Children aged 2 and up can have even more educational adventures by adding a tunnel and extra track to their LEGO® DUPLO® City interactive toy train sets (10427 and 10428, sold separately).

This creative construction toy includes a tunnel and a 10-piece track, featuring a funnel element and a 2-way switch to let toddlers change their train's direction. The action brick lights up the dark tunnel when activated by the interactive train from sets 10427 and 10428.

This children's toy promotes development. As toddlers guide the train tracks through the toy tunnel, they develop spatial awareness. They use problem-solving skills to connect the toy track, predict where the train will go, and practice patience and concentration as they discover all the routes they can build.
