Gordon

Gordon is the senior member of the engine family, the fastest and most powerful of Sir Topham Hatt's string-and he knows it. He's goodhearted, though,and always willing to forgive, and uses his supirior strength to help smaller engines out of trouble.

Fun Fact:
When the Queen visited the Island, it was Gordon that Sir Topham Hatt turned to, to take the Queen around Sodor

Gordon's involvement in the series
Gordon has been, to date, the fastest engine on Sodor, but has sometimes had accidents, sometimes due to him trying to show off; In the fifth series, his brakes were not working and he could not stop, resulting in him crashing through the Kirk Ronan Station wall. Also, in the sixth series, he ignored Salty's advice about going slow while pulling trucks, resulting in him speeding down a rickety old branch line and tumbling into a field. Though he has proven to not be too big for his wheels and to be useful instead. Once, Gordon complained to Thomas, who was late. Thomas retorted that Gordon was being bossy and told him that he had to find Mr. Conductor, who was coming to visit Sodor to look after the North Western Railway while Sir Topham Hatt was taking a holiday. He thought Mr. Conductor was not needed until Diesel 10 sped through past Thomas and Gordon at Killaban. Later, he, James and Thomas argued about who should have taken Mr. Conductor and retorted that James is a big engine and Thomas is a small blue engine.
