Harrison is a blue American diesel-electric hybrid locomotive..
Smooth Harrison thinks he's the cat's whiskers (And the vents on his face even make him look a bit like a cat). He lives in the upper level of the roundhouses, the penthouse suite, accessible by an elevated turntable. Wilson hero-worships him. Though he is vain and prideful he is a hardworker.
Harrison is based on the Union Pacific Railroad M-10003.
- Harrison is good friends with Chatsworth.
- Harrison is Chuggington's fastest diesel ever.
- He is Wilson's role model and sometimes a mentor to Wilson.
- Harrison was once a trainee with Chatsworth as stated in Watch Out Wilson.
- He is easily a smarty-pants to the other chuggers.
- In German and Latin America he is called "Harry", In Czech he is called Rychlovous (episodes 1-26, 53 onwards), which means Fastbeard. However, after it was revealed that there would be another chugger called "Harry", his naming in the German version was changed so that Harry is only a nickname now.
- In Polish, he is called "Hektor".
- In Hebrew his name is אוהד
- His behaviour and attitude is similar to Gordon from Thomas the tank engine and Thomas looks up to Gordon just as Wilson looks up to Harrison
