LEGO DUPLO Town Train Bridge & Tracks Expansion Set 10426 – 8 Tracks + Elevated Bridge | Ages 2+

Expand your toddler's LEGO DUPLO railway adventures

The LEGO DUPLO Town Train Bridge and Tracks Expansion Set (10426) invites preschoolers to dream up new train scenes. With 42 pieces, it adds eight new track segments and a buildable elevated bridge that rises above the layout, inviting little builders to reconfigure the scene and test their ideas again and again. The elevated bridge creates a fresh vantage point for play, encouraging kids to imagine trains traveling over a small landscape of imagined towns and crossings.

As little conductors arrange bricks, they’ll hear cues to tell stories, roll trains along the tracks, and use the action brick to trigger interactive moments as compatible trains approach. The set supports hands-on exploration and open-ended play, making room for repeated setups as your child’s ideas evolve.

What’s inside this expansion

• 8 track pieces to extend the rail network and mix with existing sets
• 1 action brick that triggers sounds as compatible trains approach (trains from 10427 and 10428 stop to interact)
• a buildable elevated bridge that rises for dramatic play moments
• a raisable barrier to simulate crossings and scenes
• an engineer figure to spark role-play and storytelling

Connect and expand the play experience

• Designed to connect with LEGO DUPLO Town interactive trains from sets 10427 and 10428 (sold separately)
• Encourages hands-on practice with building, sorting, and spatial reasoning
• Supports collaborative play when siblings or friends join in
• Offers tactile, safe, beginner-friendly bricks suited for little fingers
• Bridge rises over 9.5 inches tall (24 cm) and spans a wide layout for creative configurations

Dimensions note: The raised bridge measures over 9.5 in. (24 cm) tall, 41 in. (105 cm) wide, and 6 in. (16 cm) deep, providing a substantial stage for train adventures.

Why caregivers might choose this extension: it broadens pretend-play possibilities, strengthens fine motor skills through assembly, and supports early spatial awareness as children plan how tracks and bridge pieces fit together. While outcomes vary, many kids enjoy the flow of building, rolling a train across the tracks, and then reconfiguring the scene for new stories.
