Jerry is a narrow gauge tank engine who works on the Mid Sodor Railway.
Jerry was designed by Andrew Barclay Sons & Co. and built at Caledonia Works in 1919. He was later purchased by the Mid Sodor Railway.
Jerry was one of the three engines sold off in 1936, as an effort to keep the Company's head above water. Years later Jerry was sold once again but, this time to the newly re-opened Mid Sodor Railway.
