Fixer the New Engine is the sixth episode of Chuggington: Meet Thomas, Trainees!'s fifth season. It introduces the new trainee Fixer.
Thomas and the trainees, Brewster, Wilson, Koko, Hodge and Zephie wake up to "Shining Time Station" from T, K, W, B, H, Z, RJATMR. Vee tells Thomas and the trainees that a new engine is arriving at Soap Suds Docks. All of Chuggington (including Vee) head to the docks to watch the ship unload. The new engine looks a lot like Irving (his body does), but his face looks like James' cab and firebox (which Thomas thinks). The engine introduces himself as Fixer.
Next day, Fixer is given his first job: to deliver recycables to Irving. However, his load has 20 trashcars: enough to make him break a piston rod and make him go dowhill very fast. Fixer asks Vee if some of the trainees could help him with his load. Vee tells him Brewster, Wilson, Koko, Zephie, Hodge and RJ will help because Thomas has other work.
At the recycling docks, Fixer is loaded up. Fixer heads downhill and notices he can't break (a reference to Braking Brewster).
