Thomas the Tank Engine Wikia

Buster is a simple steamroller who goes about his job with pride and content. He works for the Sodor Construction Company.


Thomas & Friends

Buster helped out when Miss Jenny found molehills on the football field. Buster was also seen at the new school construction site.

Buster likes to think of himself as the "world's fastest steamroller" and often dreams of winning races. This came true when he won a race against Max and Monty on the newly completed Sodor Rally Track.

Later in The Great Discovery, He helped with the restoration of Great Waterton.


Buster is a hard worker with heart and commitment in what he does and he is a good dreamer. He goes about his job with glee and pride knowing all is right with the world. What Buster lacks in imagination, he makes up for with heart, commitment, and hard work. He is liked by all the machines for his wonderful enthusiasm and kindness to help with everything.

Technical Details


Buster is based on an Aveling and Porter R10 class steamroller. George shares the same basis.


Buster is painted brownish-red with yellow and red lining. The words "SODOR CONSTRUCTION Co." are painted on the sides of his roof in yellow, and the alloys of his rollers are painted red.

In concept art, Buster retains a similar livery, but with purple as the main colour rather than the brownish-red used on the final model.

  • Up until the introduction of Darcy in the twenty-third series, Buster was the only member of the Pack with no visible number. According to Phil Fehrle in an interview with SiF, Buster may have been intended to have a number, though he states that there was not a convenient place to put a number on his bodywork.
  • His name was originally meant to be Oliver. As a result, the description of the Jack Jumps In Livestream on the official UK YouTube Channel incorrectly states that Buster is an excavator.
  • Buster, along with Monty, are the only characters introduced in the spin-off series to be introduced in the main series.
  • He is the second known steamroller on Sodor, the first being George.
  • He, Ned, and Isobella are the only steam-powered vehicles in the Sodor Construction Company.
  • Buster had a total of thirteen facial expressions during the model era, seven of which (smirking, shocked, fuming, snoring, worried, wincing and confident) were never used on-screen.
  • Although he never had a whistle sound in the show, the Fun Cubes game does feature him with one when you get it right. This was the only time his whistle sound was ever heard, which is in fact a stock sound effect it was previously used in the Looney Tunes cartoon Porky‘s railroad.
  • Unlike George, Buster is rarely seen rolling along the roads of Sodor. This is more in life with how real-world steamrollers operate, though steam-show rollers are capable of traversing by road by themselves.
  • In a magazine story, Buster's face is smaller like George's.
  • Despite that Buster never returned in the CGI series, his theme from Thomas and the Moles, when he flattens the molehills is heard in the Series 13 episodes Creaky Cranky and The Lion of Sodor when Thomas is on his way to the Steamworks in both.
