LEGO DUPLO Train Tunnel and Tracks Expansion Set 10425

Expand your young children's train adventures with the Train Tunnel & Tracks Expansion Set (10425). Children aged 2 and up broaden their learning adventures by adding a tunnel and extra tracks to their interactive train sets from the LEGO® DUPLO® Town series (sets 10427 and 10428, sold separately).

This creative construction model includes a tunnel and a 10-piece track assembly, including a funnel element for the tunnel and two-way switches to allow children to change the train's direction of travel. An action brick illuminates the dark tunnel when activated by an interactive train from sets 10427 and 10428. This learning model for young children encourages developmental processes.

By expanding the train track that runs through a toy tunnel, children gain spatial awareness. Using problem-solving skills in combining toy tracks and the ability to pre-determine the train's destination, children develop patience and concentration while discovering the many routes they can build.
