Tidmouth Sheds are the main engine sheds on Sodor. In the Railway Series, 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. Thomas, Edward, Henry, Gordon, James, Percy, and Emily sleep here. Toby, Duck, Donald, Douglas, Oliver, Stanley, Caitlin, Belle, Flynn, and Spencer have also slept here on some occasions.
The sheds have appeared in every season and special of Thomas and Friends.
During the events of Thomas and the Magic Railroad, the left side of the sheds was being repaired for unknown reasons.
The sheds were demolished and rebuilt in Calling All Engines! with a new architectural style and an extra berth for Emily. Diesel, 'Arry, and Bert were put in charge of building them, but Thomas, believing they were destroying it, sabotaged the three, causing the engines to sleep elsewhere until it was repaired.
The turntable had frozen one time due to the icy weather, and Gordon got trapped in the sheds until it got fixed.
Many events have taken place at the sheds, such as the strike of the big engines and the confrontation between Duck, Diesel, and the big engines.
- Since the CGI switch, there seems to be a town behind the sheds.
- Almost every merchandise brand gives Tidmouth Sheds three to six berths.
- In the Railway Series, the turntable was located inside the shed and ash pits were underneath each berth.
- In some third season episodes, the interior of the shed has more than six berths, to add to that, the interior of the sheds seems to be much larger.
- In Thomas and the Magic Railroad, the space between the top of the door and the roof grew. It has stayed this way since.
- From the eighth season and onwards, the tracks inside each berth do not have any buffers.
