This creative build-and-rebuild toy lets toddlers add an elevated bridge to their LEGO DUPLO Town interactive train sets (10427 and 10428, sold separately) and elongate the route with 8 straight train track pieces that connect to any LEGO DUPLO train set. 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. This set’s action brick makes the interactive trains from sets 10427 and 10428 stop and play fun sounds as they approach it. This kids’ learning toy boosts toddlers’ development. Extending the train track to run over the bridge teaches spatial awareness. Combining the toy track to determine the train’s destination promotes prediction and problem-solving skills and helps toddlers develop patience and focus. - Train track toy set – Toddlers aged 2+ extend their LEGO DUPLO railway adventures and learn development skills with the Train Bridge and Tracks Expansion Set - Comes with lots of extra pieces to grow the fun – This creative building toy includes 8 track pieces, 1 action brick, a buildable bridge, raisable barrier and an engineer figure with a cell phone - Track building that connects to toy train sets – This set combines with LEGO DUPLO Town interactive train sets (sold separately) to expand toddlers’ learning journeys even further - Anytime gift idea – This extension set makes a fun treat for any toddler who loves to play with their LEGO DUPLO interactive toy train set, sold separately - Skill-building playsets – LEGO DUPLO build-and-rebuild interactive train toys are expertly designed to develop toddlers’ creative problem-solving, patience, focus and perseverance skills - Quality toddler toys – All elements of this LEGO DUPLO toy have been tested to the max to ensure they fulfill demanding child safety standards - Measurements – This 42-piece set includes a raised bridge measuring over 9.5 in.
