Really great accessory for Lego Duplo Railroad! However, I think it's really very expensive, like all Lego Duplo railway stuff! The fun factor is increased here especially with parents and grandparents, because under 4 years it is hard to comprehend what the turnout is and then to use even right ... Nevertheless, I think these kinds of toys for educational very valuable as the kids play themselves and build and let not only to sprinkle, such as the TV. The shelf life is indisputable genius, the stuff is not to get broken!
