I quote (from Wikipedia):
In the stories, James crashed on his first day into a field. It was blamed on the wooden brake blocks he was given. James has a reputation for being naughty. Some of the incidents include breaking a coach brake pipe and needing a passenger’s bootlace to fix it, crashing into tar wagons, and spinning on the turntable. Despite his behaviour, James is an engine proud of his red paint (err, I think you mean Sky Blue, ed) and is generally considered to be a really useful engine. He is similar in size to Edward and is one of the few engines allowed to pull the Express when Gordon is away.
Enough said!
