10425 LEGO Duplo Train Tunnel and Tracks Expansion Set

Description

Expand your toddler's train adventures with the Train Tunnel and Tracks Expansion Set (10425). Designed for preschoolers aged 2 and up, this set adds a new dimension to existing LEGO DUPLO Town interactive toy trains (10427 and 10428, sold separately). The set includes a buildable tunnel and a 10-piece track system featuring a funnel element and a 2-way points switch, allowing young engineers to change their train's direction. An action brick lights up the tunnel when activated by the interactive train, adding excitement to every journey. This expansion encourages developmental skills as toddlers extend the track through the tunnel, enhancing spatial awareness. By solving layout puzzles and predicting destinations, children build problem-solving abilities, patience, and focus while exploring countless creative routes.
