I offered last Christmas my boy, soon, 6, Lego freight train. In addition, from time to time, I acquire what enlarge the original railway track. These rails allow a certain and significant flexibility in the design of the desired circuit. The use is easy for children ages 5-12 advertised on the box. Material quality looks good, the future we will confirm ... Meanwhile I continue to trust Lego and Amazon for their quality of service, availability and choice of products, and the prices more than reasonable.
