LEGO DUPLO Town Train Tunnel & Tracks Expansion Set 10425 – 10 Extra Tracks

Expand LEGO DUPLO Town train adventures with the Tunnel and Tracks Expansion Set

Give tiny builders more ways to tell stories and move trains through their growing town. The LEGO DUPLO Town Train Tunnel and Tracks Expansion Set (10425) adds a new tunnel and a 10-piece track extension, opening fresh paths for little engineers to explore. Built for ages 2 and up, this expansion sits alongside existing DUPLO train sets to create bigger, more zigzagging journeys that spark imagination.

The set bundles practical play elements with kid-friendly design. It includes ten extra track pieces, a tunnel section, the funnel element, an action brick, and a two-way point switch that lets children steer the train’s direction with a simple nudge. All pieces are sized for tiny hands and are tested to meet toddler safety standards, offering confidence for both kids and caregivers as playtime grows.

What’s included

• 10 track pieces to extend your existing DUPLO Town layouts
• A tunnel element to guide trains through imaginative spaces
• A funnel element for added play scenarios
• An action brick to spark simple cause-and-effect moments
• A 2-way point switch to change the train’s path
• All parts designed for little hands and safe, repeated use

Play ideas and developmental benefits

• Extend routes through a tunnel to practice spatial awareness and route planning
• Combine with other DUPLO Town sets (10427 and 10428) for larger, interconnected adventures
• Encourage cooperative play as kids narrate journeys and take turns guiding the train

Beyond mere assembly, this expansion supports patient focus as children experiment with different track layouts and predict train movement. The chunky bricks, bright colors, and familiar DUPLO feel help make playtime inviting and energetic without becoming overwhelming. While outcomes will vary, families may notice richer storytelling, longer play sessions, and a growing sense of independence as little builders test new ideas and see how one tunnel can lead to many different destinations.
