Stanley, also known as "No. 2", was an American narrow-gauge tank engine.
Stanley was built at Baldwin Locomotive Works in 1917 and worked in America before arriving on the Mid Sodor Railway.
Stanley had a tendency to ride roughly on the rails, and believed that it didn't matter if he came off the track occasionally. However, this attitude resulted in his being converted into a pumping engine. He last worked at the Cas-ny-Hawin mine until he broke down in December 1946 and the mine became flooded. With no reason to stay open, the Mid Sodor Railway closed down the next month and Stanley was scrapped.some say that Stanleys whisle can still can be hear.
Stanley was arrogant and careless, and refused to listen to advice. This led to his eventual downfall.
Stanley is based on a Baldwin Locomotive Works 590 4-6-0T locomotive of the Baldwin class 10-12-D for the Welsh Highland Railway.
Stanley is painted red with black lining.
- Stanley's second appearance, in the back of the shed in "Bulldog", creates a continuity error. According to "Granpuff", Falcon and Stuart did not know about Stanley, implying Stanley's arrival and scrapping occured before their arrival. However, Stanley is seen in the same shed as Falcon, meaning Falcon would have known about Stanley and what happened to him. What's more, it has been confirmed that Falcon was built and came to the railway before Stanley.
- Stanley is the first narrow gauge engine from the Railway Series who does not appear in the Television Series. His role was taken by Smudger.
