Tidmouth Sheds are the main engine sheds on Sodor. In the Railway Stories, it is shown as a shed with three or four rails leading in (the illustrations were inconsistent), but in later books it was depicted as a shed enclosing ten berths around a turntable. In the television series, the sheds were replaced by a roundhouse with a turntable at the front.
The sheds were rebuilt in Calling All Friends with a new architectural style and an extra berth for McKhyla and Jane . Cameron , Savion , and Qulik were put in charge of building them, but DJ , believing they were destroying it, sabotaged the three, causing the engines to sleep elsewhere until it was repaired.
