Stanley is a white engine who seems to work on Thomas's Branchline and at Great Waterton. He arrived on Sodor to do Thomas' jobs while Thomas helped with The Great Waterton Restoration.
Stanley was built between 1932. He arrived on Sodor in 2008 to help with the restoration of Great Waterton.
*note: A newspaper in The Great Discovery has the date 1955. T1E2H3 does not agree with this as many characters present arrived long after that date.
In How the Diesel Stole Christmas and Episode VII, Stanley's model from Hilltrack's Trainz Routes was used. The model was uploaded to the site in September 2013. In Episode XI onwards, Seanoc17's 2012 model of Stanley, uploaded in May 2014, is used.
According to the Thomas the Tank Engine Wiki, Stanley is a cross between a Hudswell Clarke 0-6-0ST and Kitson's "Austin".
Stanley is very optimistic and extremley eager to get a job done properly.
