THOMAS & FRIENDS™ GORDON THE EXPRESS ENGINE N-Scale. Gordon is the No. 4 blue engine who pulls the express. As the senior member of the engine family, he is the fastest and most powerful of Sir Topham Hatt's team - and he knows it. He's goodhearted, always willing to forgive, and uses his superior strength to help smaller engines out of trouble. When the Queen visited the Island of Sodor, Sir Topham Hatt asked Gordon to take her around. Gordon is based on a Gresley Liner A3 4-6-2 engine. Bachmann faithfully reproduces the Thomas and Friends Characters to run on N Scale Track. All Locomotives feature Realistic Character Faces Operating N Scale Electric Drive Mechanisms, Highly Detailed Plastic Body Shells, All Metal Wheels, and Rapido-style Couplers.
