Misty Valley is a valley between Kirk Machan and Callan Castle on the Misty Valley Branch Line in the television series. It first appeared in the sixth series episode The Fogman. Cyril, a resident of the valley, was employed as a fogman until the Fat Controller acquired an electronic foghorn to warn the engines of landslides. The foghorn actually ended up causing a landslide and trouble for Thomas and Toby.

It later appeared in the eleventh series episode Thomas and the Storyteller. Thomas planned to take the storyteller to Misty Valley, which was mentioned to be the rumoured home to several magical creatures, but ended up having to take a detour to rescue Percy from a flooded river. Later in the same series, Thomas is seen blowing his new whistle in the valley.



  • When the valley returned in the eleventh series, it now had three tracks instead of two. It could be possible that the third track had been constructed off-screen or that there's another misty valley on the main line. If the latter is true then it would mean that there are at least two misty valleys on Sodor.
