In "Thomas in Trouble", Thomas encounters an officious policeman, who says that, when running from the quarry, along public roads, engines who have the right to go on public roads must be fitted with cowcatchers and sideplates for safety to prevent people and animals from getting killed if they should have the right to stray onto the line. The Fat Controller, urgently needing to rectify this, is discussing the fitting of these, when Thomas remarks that "everyone will laugh...they'll say I look like a tram". The Fat Controller (the "stout gentleman") remembered Toby immediately and arranged for him to come to Sodor. Toby arrives with his coach, Henrietta, and became a friend of Thomas after Toby rings his bell and frightens the policeman.
