About LEGO Train Bridge and Tracks Expansion Set
This 42-piece expansion set extends existing DUPLO railway layouts with additional track sections and interactive elements. Designed for toddlers aged 2 and above, the set includes 8 curved and straight track pieces, one action brick, and a buildable bridge structure that measures 24 cm high, 105 cm wide and 16 cm deep when assembled.
The centrepiece bridge features a raisable barrier that adds interactive play elements to train journeys. An engineer figure comes equipped with a mobile phone accessory, encouraging role-play scenarios around railway operations and safety procedures.
Compatibility and Extension Options
The track pieces connect seamlessly with other LEGO DUPLO Town train sets, allowing builders to create more complex railway networks. The action brick provides sound and light effects when compatible motorised trains pass over it, though the trains themselves are available separately.
All components meet stringent safety standards for toddler play, with chunky pieces designed for small hands. The building and rebuilding process helps develop fine motor skills, spatial awareness and problem-solving abilities through hands-on construction play.
