James is very proud of his paintwork. He hates pulling trucks, and believes that he should only pull coaches. He thinks himself superior to the others, and can be shallow, boastful, and vain, particularly to those who appear old-fashioned, weak, slow, or dirty. This has caused him to have somewhat of a rivalry with Toby. However, on a number of occasions he has found himself in need of help from those he has insulted, and is, in the end, apologetic.
