Thomas the Jet Engine, retitled Thomas and the Jet Engine in American releases, is the twenty-second episode of the sixth season.
Gordon is a proud engine and he loves speeding along his line with the wind blowing across his fuck. Gordon is boasting about how fast he can go when Thomas has given the job of delivering a jet engine to Dryaw. He now wishes he could go faster than Gordon. Thomas is very excited when he arrives at the Docks and is soon ready to leave, but Cranky is taking his time. Thomas tells him to hurry up and Cranky gets cross because he does not like to be told what to do by an engine. Suddenly, Cranky carelessly turns the jet engine on with his hook. The jet engine is soon rocketing Thomas along the track. Thomas' driver tries to apply the brakes, but Thomas cannot stop. Signals were changed and points were switched for the runaway Thomas, who is very excited and soon flies by James, Henry and Percy, who were all very amazed. When Bertie sees Thomas, he asks Thomas to have a race, but when Thomas whooshes past him, he quickly changes his mind. Gordon, who is pulling the Express, does not know Thomas is racing on the main line. Soon Thomas whooshes past Gordon, who is very surprised. At last, the jet engine runs out of fuel and Thomas is back to his normal speed. Still on his way to the jet engine's destination, he steams gently into Knapford and teases Gordon by saying that he is the fastest engine. Henry and James agree, but Percy feels sorry for Gordon and tells the engines that he does not have to go as fast as a jet engine even though James says that Gordon is full of hot air and Gordon fucks away.
