Background information[]

Dunbar is a fictional diesel-electric locomotive created by Sarah Ball.

He first appeared in the first episode of the series, Can't Catch Koko, and was one of the most prominent recurring characters until his removal from the series, serving as the trainees' for the first three series.

Dunbar is based on an Electro-Motive Division (EMD) GP38-2 locomotive and is painted olive green with dark green highlights.

Dunbar has not appeared in the series since the fifth series, but his horn sound, being a stock sound effect, is still used in the sixth series.

CGI model[]

In 2007, Dunbar was designed and modelled by Volume Studios in the 3D modelling software Sketchup during the production of the first series. The model was later exported to another software, Maya, for animation.[1] The model last appeared in the fifth series episode, Chug Patrol Chief.


  • Series 2:
    • He receives the new coupler and chugger plaque design.
  • Series 3:
    • His jaw gains the ability to pronounce vowels freely but still retains its puppet-like mouth mechanism.



  • Dunbar's mouth mechanism is unique from every other chugger in the series because it resembles a puppet and moves on a hinge joint. Other characters, such as Brewster and Koko, have modelled hinge joints, but they are static. As a result, Dunbar can only express emotion with his wipers. The added ability for Dunbar to pronounce vowels in the third series was most likely an attempt to rectify this anomaly.
  • Dunbar's original coupler design was unique because it had a triangular shape instead of a rectangular one. The new coupler design that was introduced in the second series unified all couplers.
  • Dunbar's model was modified into a purple chugger who appeared in the background throughout episodes of Series 2.
