📝 Our Take

The Train Bridge and Tracks Expansion Set is a fantastic addition to any LEGO DUPLO train setup. It offers new ways to play and expand your child's railway world, encouraging creativity and imaginative storytelling. The inclusion of a bridge and action plates adds a new dimension to the play experience.

This set is perfect for parents and toddlers looking to enhance their existing DUPLO train sets. With easy-to-handle pieces and straightforward construction, it's designed for little hands and developing minds. The added play features provide hours of engaging fun.

Skip this if you're looking for a standalone train set. This expansion pack requires a powered train to fully utilize its features. Consider LEGO DUPLO Cargo Train (10875-1) or Steam Train (10874-1) as a starting point.

Investment Grade

⏳ Active

As a DUPLO set, the Train Bridge and Tracks Expansion Set is unlikely to be a significant investment. DUPLO sets generally do not appreciate in value as much as LEGO System sets. However, the set's play value and the potential for expanding existing DUPLO train layouts may make it a worthwhile purchase for families with young children. The set's long-term value will depend on the continued popularity of the DUPLO train theme.

It also comes with a buildable bridge and a raisable barrier. Toddlers aged 2+ will have lots of fun playing the engineer letting through the train while practicing their fine motor skills.
