Trivia

 * Unlike Sir Topham Hatt and Mr. Percival, he is referred to by his nickname in the US version of the television series.
 * He is the only railway controller on the Island of Sodor to be a direct transplant from the Railway Series, as Sir Topham Hatt was a loose adaptation of the three from the books, while Mr. Percival was original to the television series. Additionally, Walter Richards never appeared in the television series.
 * In the French dub, his first name is "Fulbert." His last name is unchanged but pronounced with nasal vowels and silent 'n's as if it was a French name.
