THOMAS & FRIENDS™ STANLEY with Moving Eyes - HO Scale. Stanley is a cheerful, compassionate tank engine who lends himself to wherever help is needed on the Island of Sodor, whether it's working alongside Thomas the Tank Engine™, helping a friend in need, or coming to the rescue when something doesn't go as planned. Bachmann carefully reproduces your favorite Thomas & Friends™ characters in HO scale. All locomotives feature realistic faces with moving eyes, operating HO scale electric drive mechanisms, highly detailed plastic body shells, all-metal wheels, and international-style hook-and-loop couplers.
