Dazzling Diesel! is a rhyming magazine story.
The engines are all arguing about whose paintwork is the best. Then, Diesel spots some bunting being hung up by a guard who explains that they are for the Mayor's visit. Diesel has a naughty plan and rolls into the string of colourful flags. As the flags drape around him, Diesel boasts that he is now the brightest of all the engines.
