The LEGO Duplo Set Railway Bridge and Tracks is the perfect addition to new or existing Duplo train sets and promotes the development of early building skills as toddlers construct the tall bridge or arrange the individual track segments as they like. Help your preschooler place the yellow function brick on the track so that compatible Duplo trains sound a signal when they pass over the brick. Also included are a LEGO Duplo construction worker figure, two loose bricks, a shovel, and a suitcase to provide even more fun for children during their role play and storytelling.
