Tidmouth Sheds (T&F)

Tidmouth Sheds are the main engine sheds of the North Western Railway located at Tidmouth. 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. 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.

In the television series, the sheds were replaced by a roundhouse with six berths and a turntable outside at the front. Thomas, Edward, Henry, Gordon, James, Percy and Emily generally sleep here, although other engines occasionally spend the night here. Duck formerly slept here. 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 due to upgrades to the railway. The sheds were later 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 was fixed. Later on, all of the steam team went on strike by refusing to leave the sheds until the Fat Controller was allowed to stay on Sodor, however it was just a misunderstanding as Sir Topham was never leaving.

Trivia

The new sheds from the later books were actually present since 1953, as in Thomas' Christmas Party it mentions the new engine shed and according to the Reverend W. Awdry they were the most accurate in The Island of Sodor: Its People, History and Railways, indicating the old shed up until James and the Diesel Engines was inconsistent.
- In the Railway Series, the turntable was located inside the shed and ash pits were underneath each berth.
In the Season 20, the engines used the same berths every night/episode instead of constantly changing. Looking from the front, from right to left, they were ordered; Henry, Gordon, Edward, James, Thomas, Percy, and Emily.
