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.


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 is also a member of this class.


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 for 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.
  • 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, seven of which (smug, shocked, fuming, snoring, worried, wincing and confident) were not used on-screen.
  • Although he never had a whistle sound in the show, the Fun Cubes game does feature him with one. This was the only time his whistle sound was ever heard.
