"Little engines can do big things!"
Thomas is a rather cheeky little tank engine, but is good at heart and generally behaves well, except when he is getting into mishap. He loves teasing the others and, on occasion, brags about his superiority, but is always brought down to earth in due course. If Thomas has one major character flaw, it's that he is forgetful, and slightly impatient. However, he is also optimistic, idealistic and brave.
