Percy is a great western saddle tank engine. He is green with red stripes, and has the number 6 painted on his tanks. Percy is a cheeky little engine. His best friend is Thomas. Percy's favorite job is pulling the mail. he was originally owned by the avonside engine company and was then given to a factory in England who gave him a rebuild.after,he was sold to the North Western Railway second hand for cheap to the Hatt family so there could be another tank engine to help out during a strike held by Gordon, Henry and James in 1935
