Expand toddlers' train adventures with the Train Tunnel and Tracks Expansion Set (10425). Kids aged 2 and up can enjoy even more educational adventures by adding a tunnel and extra tracks to their LEGO® DUPLO® City interactive toy train sets (10427 and 10428, sold separately). This creative building toy features a tunnel and a 10-piece track, including a funnel element and a 2-way changeover switch that lets toddlers change the direction of their train. The action brick illuminates the dark tunnel when activated by the interactive train from sets 10427 and 10428. This children's toy stimulates development. As toddlers guide the train tracks through the toy tunnel, they develop their spatial awareness. They use problem-solving skills to match the toy track, predict where the train will go and practice their patience and concentration as they discover all the routes they can create.
