- “If you were going any slower, you'd be going backwards!”
- ―Max to Buster
Thomas & Friends
Buster helped out when Miss Jenny found mole hills 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.
Buster is based on an Aveling and Porter R10 class steamroller. George shares the same basis.
Buster is painted brownish-red with yellow, orange and red lining. The words "SODOR CONSTRUCTION Co." are painted on the sides of his roof in yellow.

Buster had a role in the cancelled episode, The Importance of Being Patrick.
- Buster is 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 might not have been a convenient place for 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 other being George.
- A large-scale model of George was built for the series but was reworked to make Buster.
