Paxton is a young, gentle diesel who often works in or around the Quarry. He is good-hearted and well meaning, but gullible, naïve, and easily misled. He also has a short attention span. He tends to be more of a follower than a leader and can sometimes find thinking for himself and making big decisions difficult. This may result in him being pressured into a situation he might not necessarily be comfortable with. However, if a friend is in trouble, Paxton will have the conscience and the self-assertion to do what he himself feels is right. As a result, the other steam engines find that he is likable and Paxton particularly looks up to Thomas at times. However, Paxton can easily misjudge situations, misplace his trust in someone who might not have everyone's best interests at heart, and is a rather impressionable diesel, but his good nature will ultimately show him for who really wants to be.


Paxton is a BR Class 08 shunting diesel.

  • Paxton was never meant to be in the series. Like Hiro, he was added at the last moment.
  • Despite Paxton's nickname being "Pax", he has been consistently referred to by his full name rather than his nickname. He shares this dilemma with Sidney.
