The Interactive Adventure Railway (10427) is a toy for pre-school children that turns toddlers aged 2 and over into train drivers. This toy railway lets toddlers choose the destination for the family outing and go on an educational journey with lots of lights and sounds. The building and rebuilding playset includes various bricks to build a park, a beach, a railway station or a family home, stimulating toddlers' curiosity and teaching them creative building techniques. The educational toy allows preschoolers to develop patience, dexterity and creativity as they focus on building the railway line and choosing a destination for the train. 3 action bricks in this building set make for a lively play experience and allow the train to make realistic noises as it rolls over them. Toddlers learn to make predictions by guessing what sound the train is about to make. They can also use the specially customisable brick to play their own sounds recorded with LEGO DUPLO Interactive Trains. This free app turns a smartphone or tablet into a remote control for the train in this building toy. The track segments connect to form a LEGO DUPLO circuit that measures 13 cm high, 71 cm wide and 57 cm deep. Contains 57 pieces.
