The set railway bridge and rails is the perfect complement new or existing DUPLO train sets and promotes the development of early building skills when toddlers build the high bridge or order the individual rail segments as they please. It contains a function block which can be so placed on the track that compatible DUPLO trains when passing over the stone blank will sound a signal. Included are a construction worker figure, two loose stones, a shovel and a suitcase to let you experience even more fun in their role-playing and storytelling the children.
