LEGO DUPLO Tunnel and Tracks Extension Set 10425

The LEGO DUPLO Tunnel and Tracks Extension Set (10425) is designed to expand existing DUPLO train layouts. This set introduces a buildable tunnel structure that allows DUPLO trains to pass through, adding a new element to the environment. It also includes 10 additional track pieces to extend the physical play area and create longer routes. Among these pieces is a two-way switch track, which enables the creation of branching paths and more dynamic railway configurations. The set integrates with compatible DUPLO train systems.

Comprising 20 large-format plastic bricks, the set is suitable for builders aged two to five. The pieces are engineered for compatibility with all other LEGO DUPLO track and train sets, facilitating system-wide modularity. The interlocking brick construction is standard for the DUPLO line, which supports straightforward assembly and disassembly by young children. This extension provides the core components required to build larger and more intricate train networks from a pre-existing collection.
