My 4 year old son adores trains; among his favorites are the characters from "Thomas the Train." He inherited Gordon from his from his 6 year old sister, so it's a few years old. It is a typical high quality "Thomas the Train" wooden train; well made and durable. After years of less than gentle treatment at the hands of two children, the train is still in almost perfect condition, attesting to its superior quality. Gordon consists of two pieces, the engine and the tender. As with all the Thomas wooden trains, Gordon is compatible with wooden tracks by Chuggington, Brio, and Circo (the Target brand) all of which we own, in addition to the Thomas tracks.
