Thomas & Friends Season 6 Episode 6 The Fogman Episode Title:The Fogman.Episode Description:Every winter, a fogman called Cyril puts detonators on the track to warn engines of fog, but one winter, the Fat Controller announces that Cyril is to be replaced by a newly invented railway foghorn so that Cyril can have a rest from his job. However, the next day, when the foghorn alerts Percy, its loud noise triggers a landslide the moment Percy disappears, smashing the foghorn in the process. As a result, Thomas crashes into the landslide and hears Toby coming, but Cyril comes and puts down a detonator to alert Toby and keep him from having a worse accident. Sir Topham Hatt then declares that Cyril deserves to keep his job, as he is more reliable than the foghorn, much to Thomas, Toby and Percy's delight.
