- “You should hear them in the workshop. You have to wheesh loudly to be heard.”
The Workshop was a shed on the Mainland, where engines, old and new, were built/repaired and stored until they could be bought by railways or other industrial workplaces. One time, the Fat Controller visited the workshop with hopes of finding a tank engine. He looked at them all until he saw a green saddle tank and when the engine confirmed he was willing to work hard, the Fat Controller bought him and named him Percy.
- In the television series, the workshop consists of the Railway Works and Knapford Station.
- It is unknown if this workshop is actually located on the Mainland in the television series, as it could be somewhere on Sodor.
- In the television series, the other engines shown in the workshop are really Gordon, the Märklin Engine, James, Henry and Edward covered under tarpaulins with the tenders removed so that the audience would not make out who they were.
