James is very proud of his splendid red 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 whom he has insulted and is, in the end, apologetic. James was the last engine to retain a prejudice against Diesels. However, after stalling on a cold day, he was rescued by the Works Diesel, and James had to admit that nothing was wrong with Diesels. This appears to be one of the few lessons that has stuck. Despite everything else, James has shown a caring side, is normally hard-working, and like everybody else, wants to be a responsible, reliable and really useful engine on Sir Topham Hatt's railway.
