Train Tunnel and Tracks Expansion Set

DUPLO railway enthusiasts can expand their train layouts with this comprehensive track extension set designed for toddlers aged 2 and above. The set provides essential components for creating more elaborate railway networks while supporting early development skills through hands-on building and play.

The 20-piece collection includes 10 track pieces, a 2-way points piece for directing trains along different routes, one action brick, and tunnel and funnel elements to add vertical interest to layouts. These components integrate seamlessly with existing DUPLO train sets, particularly the Town interactive train sets (10427 and 10428), allowing children to construct larger, more complex railway systems.

Key Features

The centrepiece tunnel measures 20 cm high, 16 cm wide and 15 cm deep, creating an impressive focal point for any railway layout. The 2-way points piece introduces basic railway mechanics, teaching toddlers how trains can change direction and follow different paths. All track pieces maintain DUPLO's signature large-scale design, making them easy for small hands to handle and connect.

The set focuses on developing creative problem-solving abilities, patience, and fine motor skills through building and rebuilding activities. Each component meets stringent child safety standards and is built to withstand enthusiastic toddler play while encouraging extended railway adventures.
