The Works Diesel rescued James after his injector failed, and managed to eradicate James' dislike of diesels with his charismatic persona. He then brought the Christmas tree for Thomas from the Other Railway. In Gordon the High-Speed Engine Donald mentions that there are other diesels at the works. The Works Diesel was later seen talking to Gordon at Barrow-in-Furness.
Although the Works Diesel has not spoken, he is described as being friendly and is impossible to not like - even James, who retained a hearty dislike of diesels, could not help but befriend him before the two had even reached the Works.
The Works Diesel is based on a BR Class 47 "Brush" Co-Co.
The Works Diesel is painted in a British Rail "Rail Blue" livery with yellow warning panels.
