Tidmouth Sheds are the main engine sheds of the North Western Railway located at Tidmouth. In the Railway Series, they are shown as a shed with three or four rails leading inside them (the illustrations were inconsistent), but in later books they were depicted as a shed enclosing ten berths around a turntable. Numerous major events have occurred at the sheds, such as the strike of the big engines and the confrontation among 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, Gordon, James, Percy and Emily generally sleep here, although other engines sometimes spend the night here. Edward, Henry, Toby and Duck formerly slept here, in which the former two later left the sheds to live in other locations to make room for Nia and Rebecca, although Edward and Henry still stay at the sheds on rare occasions. Duck has stayed at the sheds on at least two occasions since leaving. The sheds have appeared in every series 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, attempting to pay them back for their bad behaviour earlier on, sabotaged the three, unaware that they were delivering building supplies for the sheds, causing the engines to sleep elsewhere until it was repaired. When the job was completed, Emily then became part of the team at Tidmouth Sheds.
The turntable had frozen one time due to the icy weather and Gordon got trapped in the sheds until it was fixed. Later on, the steam team went on strike by objecting to leave the sheds until the Fat Controller was allowed to stay on Sodor, however it was just a misunderstanding as Sir Topham Hatt was never leaving.
Sometime later, James crashed into the back of the shed wall after having trouble with his brakes. A week later, the shed was repaired and everybody moved back in, but Edward then chose to permanently move to Wellsworth Sheds with Philip, as it was near his branch line. Some time later, Henry left to stay at Vicarstown Sheds with Rosie, in order to live closer to his new jobs on the Mainland.
The current order of the berths the Steam Team sleep in is; Rebecca, Gordon, Nia, James, Thomas, Percy and Emily.
