THOMAS & FRIENDS™ BEAU Locomotive - HO Scale. Beau is a beautiful engine from the American Southwest sporting a moustache. Thomas met Beau in his traveling adventures around the world, when Thomas accidently derailed outside a railroad mine. Based on an American 4-4-0 Steam Locomotive, this old-time engine is the perfect addition to your Thomas and Friends collection. 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.
