Percy's Workshop Friends
Many engines appeared at the workshop where Percy used to live before arriving on Sodor. The Fat Controller came to the Workshop to purchase a new tank engine, when the three big engines (Henry, Gordon, and James) went on strike and Thomas left to run his branch line.
They were described as looking "big, little, happy, sad and anxious". The large blue tank engine slightly resembles Thomas with extended side tanks, the red engine resembles Gordon.
In addition to these, other engines were seen in the My Thomas Story Library book, where there are two other engines; one maroon and the other blue with red lining. The maroon one vaguely resembles Percy and the blue one vaguely resembles Wilbert.

- In the television series, the engines shown in the workshop were actually Gordon, Thomas, James, Henry, and Edward, but covered in tarpaulins and with the tenders except Gordon's removed so that the audience would not make out who they were.
Edward's Workshop Friends
When Edward was sent to the works to be mended, he met three engines. Edward was quick to befriend these engines, due to their positive attitude towards him.
The first engine, on Edward's right, is a silver diesel engine. This one was based on a Bulleid 10201 class diesel-electric; all of which had been scrapped by the mid 1960's. The second engine, on Edward's left, is a tender engine and who strongly resembles a green version of Murdoch with green smoke deflectors. Although it resembles more of a BR Standard Class 6. Finally, the last engine can be seen behind Edward, however only his/her smokebox and eyes are visible and he/she appears to be painted salmon.
The Blue Overhauled Engine
The Blue Overhauled Engine was a tender engine, who was undergoing an overhaul similar to Henry's new design. He/she was first seen when Henry was being escorted to the Works by Percy. Henry was shocked to learn that the works was full of ill engines.
This engine slightly resembles Henry, with slightly different cylinders and blue paint work and also looks a bit like Gordon.
