Coal, retitled Henry's Special Coal for American releases, is the eighteenth episode of the first season.
Henry is ill and the Fat Controller fears he will have to be replaced if he cannot improve. The next day, the Fat Controller rides in Henry's cab. Henry is unable to go further than Wellsworth and Edward takes over. The fireman tells the Fat Controller Henry's firebox is too small and he needs Welsh coal. The Fat Controller arranges for James to collect some, and Henry feels better, even managing to find time to tease Thomas.
