Extend toddlers’ train adventures with the Train Tunnel and Tracks Expansion Set (10425) toy for toddlers. Little ones aged 2+ grow their learning adventures as they add a tunnel and extra track to their LEGO DUPLO Town interactive toy train sets (10427 and 10428, sold separately).

Great for Montessori, this toddler learning toy comes with a tunnel build and a 10-piece toy train track, including a funnel element and a 2-way points switch so toddlers can change their train’s direction of travel. The action brick lights up the dark tunnel when activated by the interactive toy train from sets 10427 and 10428.

This educational toy makes a great gift for 2 plus year old toddlers, boys and girls. By extending the railway track through the toy tunnel, preschoolers learn spatial awareness. Using problem-solving skills to combine the toy train tracks and prediction skills to determine the train’s destination, toddlers develop patience and focus as they discover the many routes they can make.
