Henry and Diesel is a magazine story.
Henry is one of Sodor's oldest engines. One day, Diesel teases him about it, saying that Henry is old and creaky. Later on, Henry hears that Diesel has derailed. Henry eventually goes to his rescue, and as he chuffs away with the breakdown train, the crane arm slips and hits Diesel. Henry didn't mean to do it, but he thinks Diesel deserved it.
