Wendell is a Hudswell Clarke 0-6-0 Tank Engine bought by Sir Topham Hatt. Wendell had been sent to work at the harbor at Knapford. But being confined to his small yard he seeked adventure onto Edwards line where he met Bill and Ben. He returned as a pilot engine at Tidmouth, shunting small trains and fetching coaches for bigger engines. When Sir Topham Hat needed an engine to tackle a heavy goods train to barrow, Wendell took to the task, but ending up in Farmer Browns Field! When returning home, Sir Topham Hat placed him as permanent goods engine on the Wellsworth Branch, and occasionally shunting back at Tidmouth. To those who hear his story, he is 'The Iron Solider'!
